Answer:

A. The number of women and the number of men included in the data

Step-by-step explanation:

The boxplot is a useful way to display data. It represents the distribution of data in a five-number summary. These five numbers include the minimum, first quartile, median, third quartile, and maximum. Respectfully, each line on the graph, from left to right, represents one of these numbers. However, because the graph only shows the distribution of data, it does not include the sample size.

A study was done to determine the stress levels that students have while taking exams. The stress level was found to be normally
Advocard [28]

Answer: 0.1841

Step-by-step explanation:

Given: Mean : \mu=8.2

Standard deviation : \sigma = 1.34

The formula to calculate z-score is given by :_

z=\dfrac{x-\mu}{\sigma}

For x= 9, we have

z=\dfrac{9-8.2}{1.34}\approx0.60

For x= 10, we have

z=\dfrac{10-8.2}{1.34}\approx1.34

The P-value = P(0.6

=0.9098773-0.7257469=0.1841304\approx0.1841

Hence, the probability that at your next exam, you will have a stress level between 9 and 10 = 0.1841
