Mr. Roby is trying to estimate the difference in the proportion of his male students who on average sleep fewer than 6 hours per night compared with his female students. He selects a random sample of 20 of his 75 male students and finds that 5 of them sleep fewer than 6 hours per night. He selects another random sample of 17 of his 100 female students and finds that 8 of them sleep fewer than 6 hours a night. Check the conditions for constructing a confidence interval for the difference in proportions. Random condition: 10% condition: Large Counts condition: | Are all the conditions for inference met?

proportion of his male students who on average sleep
fewer than 6 hours per night compared with his female
students. He selects a random sample of 20 of his 75
male students and finds that 5 of them sleep fewer than 6
hours per night. He selects another random sample of 17
of his 100 female students and finds that 8 of them sleep
fewer than 6 hours a night.
Check the conditions for constructing a confidence
interval for the difference in proportions.
