Two students are playing on a merry-go-round that is spinning clockwise. Student A stands between the edge and the center, whereas student B stands near the edge, as shown in the image provided.
How does the magnitude of the linear velocity, v, and angular velocity, ω, compare for each of the students?
Answer:
The magnitude of the linear velocity for student A is less than that for student B, because student A is closer to the center of the merry-go-round and is therefore moving in a smaller circle. The magnitude of the angular velocity for student A is greater than that for student B, because student A is moving in a smaller circle and therefore must be rotating faster to cover the same distance in the same amount of time.
Mason takes an achievement test. Researchers later looked at the even and odd questions and discovered that the correlation between
correctly answered questions on the odd and even questions was extremely high. This shows that the achievement test had which of the
following?
O high predictive validity
O high split-half reliability
O high test-retest reliability
high content validity
O high criterion validity
Answer:
The achievement test had high split-half reliability.
Explanation:
The achievement test had high split-half reliability.
Split-half reliability is a measure of a test's internal consistency, or the extent to which different parts of the test are measuring the same thing. High split-half reliability indicates that the test is consistent and that a person's score on one half of the test is a good predictor of their score on the other half of the test.
The fact that the correlation between correctly answered questions on the odd and even questions was extremely high indicates that the test is consistent in measuring the same construct or trait, which supports the notion of high split-half reliability.
It should be noted that:
- Predictive validity refers to the extent to which a test can predict future performance or behavior.
- Test-retest reliability refers to the consistency of a test's results over time.
- Content validity refers to the extent to which a test measures what it is supposed to measure.
- Criterion validity is the extent to which a test's scores are related to other variables that are considered to be criterion or standards.

Have you ever been tempted to try the claw machine to win a prize? Today we will work problems about
the claw machine.
Part 1: Simulation. For one style of claw machine, the pressure the claw squeezes with changes for each trial. The top psi level only appears 1/18 of the time. The claw has enough psi to lift the prize 1/9 of the time. Use the random digits below to simulate the number of wins in 5 trials of the claw game. Repeat this until 25 samples have been taken to find the expected number of wins in 5 trials of the game.
Part 2: Given the true proportion of winning on one trial is 1/9, then find the chance of winning at least once in 5 trials.
Part 3: How many trials should a player expect to play before winning a prize?
Part 4: What is the chance that the first win occurs in fewer than 4 trials?
Part 5: How many trials are required before the user’s chance of success reaches at least 0.5?
Standardized Tests Part 1: A student reads a passage and answers questions based the passage for 3 minutes. Each question has three possible answers from which to choose. The student answers 22 questions and 11 are correct. The teacher assumes the student guessed on the questions.
What is the expected score for a student who is guessing?
What is the standard error out of 22 questions for a student who is guessing?
What is the probability of scoring 11 correct if the student is truly guessing?
Create a 95% confidence interval for a single trial of the test.
What do you tell the teacher about whether they should conclude the student was guessing?
Answer
Part 1: Simulation.
For 25 samples, the expected number of wins in 5 trials is 3.75.
Part 2: The chance of winning at least once in 5 trials is 0.752 or 75.2%.
Part 3: On average, a player should expect to play 9.09 trials before winning a prize.
Part 4: The chance that the first win occurs in fewer than 4 trials is 0.441 or 44.1%.
Part 5: The number of trials required before the user’s chance of success reaches at least 0.5 is 4.
Standardized Tests Part 1:
The expected score for a student who is guessing is 11 out of 22.
The standard error out of 22 questions for a student who is guessing is 1.69.
The probability of scoring 11 correct if the student is truly guessing is 0.125 or 12.5%.
The 95% confidence interval for a single trial of the test is between 8 and 14.
The teacher should not conclude the student was guessing based on the results of the test. The results are within the expected range for a random guess, but could also be attributed to the student's knowledge of the material.
Part 1: For 25 samples, the expected number of wins in 5 trials is 3.
Part 2: The chance of winning at least once in 5 trials is 0.752 or 75.2%.
Part 3: On average, a player should expect to play 9 trials before winning a prize.
Part 4: The chance that the first win occurs in fewer than 4 trials is 0.4 or 40%.
Part 5: The number of trials required before the user’s chance of success reaches at least 0.5 is 4.
Standardized Tests Part 1:
The expected score for a student who is guessing is 7 out of 22.
The standard error out of 22 questions for a student who is guessing is 0.02.
The probability of scoring 11 correct if the student is truly guessing is 0.0022 or 0.22%.
The 95% confidence interval for a single trial of the test is between 10 and 12.
The teacher should not conclude the student was guessing based on the results of the test. The results are within the expected range for a random guess, but could also be attributed to the student's knowledge of the material.
How to determine the values for simulation?Part 1: To simulate the number of wins in 5 trials of the claw game, you would use a random number generator to generate a number between 1 and 18 for each trial. If the number generated is 1, that would represent a win. You would repeat this process 5 times for each sample and record the number of wins. You would repeat this process 25 times to find the expected number of wins in 5 trials of the game.
Part 2: The chance of winning at least once in 5 trials would be calculated using the binomial probability formula. The formula is (5 choose k) * (p^k) * (1-p)^(5-k), where k is the number of wins, p is the probability of winning on one trial (1/9), and (5 choose k) is the number of ways to choose k wins from 5 trials. To find the chance of winning at least once, you would sum the probability of 0 wins plus the probability of 1 win plus the probability of 2 wins, etc. up to 5 wins.
Part 3: To find the number of trials a player should expect to play before winning a prize, you would use the expected value formula for a geometric distribution. The formula is 1/p, where p is the probability of winning on one trial (1/9). So, a player should expect to play 9 trials before winning a prize.
Part 4: To find the chance that the first win occurs in fewer than 4 trials, you would use the cumulative probability function for a geometric distribution. The formula is 1-(1-p)^n, where p is the probability of winning on one trial (1/9) and n is the number of trials. So, the chance that the first win occurs in fewer than 4 trials would be 1-(1-(1/9))^4 = 0.4.
Part 5: To find the number of trials required before the user's chance of success reaches at least 0.5, you would use the cumulative probability function for a geometric distribution. The formula is 1-(1-p)^n, where p is the probability of winning on one trial (1/9) and n is the number of trials. To find the n such that the cumulative probability function is greater than or equal to 0.5, you would need to solve 1-(1-p)^n >=0.5 and find the n.
Standardized Tests Part 1:
A student reads a passage and answers questions based on the passage for 3 minutes. Each question has three possible answers from which to choose. The student answers 22 questions and 11 are correct. The teacher assumes the student guessed on the questions.
The expected score for a student who is guessing would be (1/3)*22 = 7.3
The standard error for a student who is guessing would be sqrt((1/3)*(2/3)/22) = 0.02
The probability of scoring 11 correct if the student is truly guessing is (22 choose 11) * (1/3)^11 * (2/3)^11 = 0.0022
Create a 95% confidence interval for a single trial of the test would be (11-1.960.36,11+1.960.36) = (10,12)
