Suppose the class sizes in high schools in a major public school district are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 high school classes is taken to estimate the mean class size, use a calculator to find the t-score that should be used to find a 90% confidence interval estimate for the population mean.
Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703
A piece of string is 3-5 m long. Joe cuts three pieces from it,
each 70 cm long. How much of the original piece is left?
Note: It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
3.5mAs we know that
3.5m = 350 cmso the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.

Anthony drew a picture of the front view of a doghouse using two congruent triangles and a rectangle, as shown in the diagram. 3 in. 4 in. 12 in. What is the area of the picture of the doghouse in square inches?
Answer:
66 in.
Step-by-step explanation:
the rectangle has an area of 48in. because 4x11 = 48. The triangles have a base of 6 because 12 ÷ 2=6. the formula for area of a triangle is BxHx1/2 and the height is 3in so 6x3= 18 and 18x1/2=9 and there is two triangles and the other has the same area. Then you add up the area of everything so 48+9+9 = 66

Alfonso made a scale drawing of a tower. The actaul height of a tower is 25 feet. The scale Alfonso used in his drawing is 1 in.:10 ft. What is the height of the tower in Alfonso's drawing?
Answer:
2.5 inches
Step-by-step explanation:
Using Alfonso's scale of the drawing, which is 1in=10 ft, we can conclude the height of the tower to be 2.5 inches because
the actual height of the tower is 25 feet
10+10=20, which by following the scale, is 2 inches
we then have 5 left, 5 being half of 10, and .5 being half an inch.
Therefore the height of the tower using Alfonso's scale is 2.5 inches.
Hope this helps and take care

Find the total amount given the original price, tax rate and tip rate. Round to the nearest hundredth if necessary.
Original price: $101.33
Tax rate: 6.7%
Tip: 18%
Answer:
The total cost would be $126.36
Step-by-step explanation:
18% plus 6.7% is 24.7%. 24.7% of 101.33 is 25.028. Add $101.33 and $25.03
The total amount including tax rate and tip rate is $127.58.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The original price is $101.33.
Now, Tax rate is 6.7%.
Price with tax is,
= (106.7/100)×101.33.
= $108.12.
The price with tip is,
= (118/100)×108.12.
= $127.58.
So, The total price is $127.58.

For a standard normal distribution, find:______. P(z < -0.34) Express the probability as a decimal rounded to 4 decimal places.
Answer:
36.69%
Step-by-step explanation:
Given a standard normal distribution :
P(Z < - 0.34) :
Using the Z distribution table :
Look up the value - 0.3 down the row and 0.04 a cross the column. The value at the intersection of the two points gives the required proportion:
P(Z < - 0.34) = 0.3669
0.3669 as a percentage = 0.3669 * 100% = 36.69%
The value can also be obtained using the Z probability calculator.
