Use the box-and-whisker plot to answer the question. Which statement best describes the data set represented by this box-and-whisker plot?

A. Half of the data is less than 3, and half of the data is greater than 3.

B. Half of the data is less than 6, and half of the data is greater than 6.

C. Half of the data is less than 9, and half of the data is greater than 9.

D. Half of the data is less than 12, and half of the data is greater than 12.

E. Half of the data is less than 15, and half of the data is greater than 1 than 15

b. 13

step-by-step explanation:

as there are 13 students in bowling class therefore the most reasonable answer is b as only 13 students are in the bowling class.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
