The process of producing pain-reliever tablets yields tablets with varying amounts of the active ingredient. It is claimed that the average amount of active ingredient per tablet is at least 200 milligrams. The Consumer Watchdog Bureau tests a random sample of 70 tablets. The mean content of the active ingredient for this sample is 194.3 milligrams, while the standard deviation is 21 milligrams. What is the approximate p-value for the appropriate test

Answers

Answer:

p = 0.0116

Step-by-step explanation:

We are given;

Population mean; μ = 200 mg

Sample mean; x¯ = 194.3 mg

Standard deviation; σ = 21 mg

Sample size; n = 70

Formula for z-score is;

z = (x¯ - μ)/(σ/(√n))

z = (194.3 - 200)/(21/√70)

z = -5.7/2.51

z = -2.27

From the z-score table attached, the p-value at z = -2.27 is p = 0.0116

Answers

Answer:

Step-by-step explanation:

Failing a test is atypical for most kids. You have the occasional, but generally failing is something people don't really do. A typical test score varies from 95-70. It really just depends on the person. I sure hope you don't usually score 30's on tests.

Emily took 300 US dollars to the bank to exchange it for Canadian dollars. The exchange rate on that day was 1.25 Canadian dollars per one US dollar. How many Ganadian dollars did she receive for 300 US dollars?

Answers

Emily wanted to exchange her 300 US Dollars for Canadian Dollars.

The exchange rate for it was 1.25 Canadian Dollars for 1 US Dollar.

This means that 1 US Dollar = 1.25 Canadian Dollars.

So if we were to follow this pattern,

2 US Dollars = 2 × 1.25 = 2.5 Canadian Dollars

3 US Dollars = 3 × 1.25 = 3.75 Canadian Dollars

4 US Dollars = 4 × 1.25 = 5 Canadian Dollars

So for 300 US Dollars, we'll need to multiply 300 by 1.25.

300 US Dollars = 300 × 1.25 = 375 Canadian Dollars.

Hope it helps. :)

B. x= 12,4
C. X = +4-2
D. = +4.6

Answers

Answer:

x = ± 2√2

Step-by-step explanation:

Assuming "x2" is x^2 or "x squared", the answer can be derived from "square-rooting" both sides.

√ x^2 = √ 8

Then we simplify.

x = ± 2√2

You spent $145 purchasing 3 student tickets and 7 adult tickets. Adult tickets cost $5 more than a student ticket. Find the cost of a student ticket. Find the cost of an adult ticket.

Answers

Answer:

$11 and $16

Step-by-step explanation:

let x be the cost of a student ticket then an adult ticket is x + 5 , then

3x + 7(x + 5) = 145 , that is

3x + 7x + 35 = 145

10x + 35 = 145 ( subtract 35 from both sides )

10x = 110 ( divide both sides by 10 )

x = 11

Student ticket costs $11 and adult ticket = x + 5 = 11 + 5 = $16

In a survey, 400 people were asked to choose one card out of five cards labeled 1 to 5. The results are shown in the table. Compare the theoretical probability and experimental probability of choosing a card with the number 3.

Number 1 2 3 4 5
Frequency 32 96 128 112 32

Answers

Answer:

The value of the experimental probability is greater

Step-by-step explanation:

For the theoretical probability;

the probability that a card with the number 3 is selected is 1/5

We consider that the probabilities of each selection are equal, for the theoretical probability

For the experimental, we simply place the frequency of the selection 3 over the total

that will be 128/400 = 8/25

As we know that 8/25 is greater than 1/5

We can conclude that the value of the experimental probability is greater than that of the theoretical

Mike, who owns a dive shop in the United States, decides to take a group of his customers diving in U.S. waters. Mike is aware that sharks occasionally visit the area where the divers will be visiting. He is also aware that while stingrays are usually tame, they can become aggressive when fed. Mike does not reveal that information to the group of divers going with him. The divers go down into the water, and some have squid with which to feed the stingrays. During the dive, one of the stingrays becomes agitated and latches onto diver Susie's arm. Susie is so disconcerted that she drops her regulator (her breathing device) from her mouth and is in considerable difficulty. Another diver, Billy, encounters a shark, which snaps at him. While the shark does not actually bite Billy, the attack results in damage to his diving equipment. Mike, who is in charge of the dive, does nothing to help and leaves the other divers to return to the boat because the dive turned out to be more trouble than expected. Wendy, another diver on the trip, also returns to the boat without doing anything to help the divers in distress. Sam, on the other hand, goes to rescue the divers who are in distress. He manages to do so but in the process he pulls his back and requires medical care. All divers are very unhappy with Mike. Billy and Susie are annoyed that Mike did not come to their assistance. Which is true regarding Mike's duty to provide assistance to them during the dive?A) Mike had no duty to provide any assistance to them.B) Mike had a duty to come to their aid because he arranged the dive and was charging them.C) Mike had a duty to come to their assistance only if he had specifically agreed to do so prior to the dive.D) Mike had a duty to come to their assistance only if they were minors.E) Mike had a duty to come to their assistance only if no one else did so.
