Answer: Hello your question is incomplete below is the missing part
Which of the following statements about Hannah’s claim is supported by the interval?
A) Hannah is likely to be incorrect because the difference in the sample means was 18.6−14.4=4.218.6−14.4=4.2 hours.
B) Hannah is likely to be incorrect because 9 is not contained in the interval.
C)The probability that Hannah is correct is 0.99 because 9 is not contained in the interval.
D)The probability that Hannah is correct is 0.01 because 9 is not contained in the interval.
E)Hannah is likely to be correct because the difference in the sample means (18.6−14.4=4.2)(18.6−14.4=4.2) is contained in the interval.

Answer:
The 2 box-and-whisker plot is the correct one.
Step-by-step explanation:
The first step you need to do is write the numbers from least to greatest.
5, 7, 8, 10, 13, 14, 17, 17, 21. 5 and 21 will be the end points.
To make the box we need to find the median first. All you have to do is pick the middle number and it is 13. That just leaves box-and-whisker plots 2 and 3.
To find the first and third quartile, you need to take the other numbers from 13 to the left (10+8+7+5) and add them up then divide by 4 to get 7.5 and that is the first quartile.
To find the third quartile, you will go from 13 to the right (14+17+17+21) and divide by 4 to get 17.25.
This equals the 2nd box-and-whisker plot.
A.
3x+3 (x+y)
distribute what is inside the bracket.
3x + 3x +3y
add the like terms
6x+3y
The area would be height x width
area = 32 x 22 = 704 in^2
answer is D
