A doctor would like to estimate the mean difference in the number of hours of sleep for seniors in high school and seniors in college. To do so, he selects a random sample of 50 high school seniors from all high schools in his county. He also selects a random sample of 50 seniors from the colleges in his county. He would like to construct a 95% confidence interval for the true mean difference in the number of hours of sleep for seniors in high school and seniors in college. Are the conditions for inference met?
Yes, all three conditions for inference are met.
No, the random condition is not met for both samples.
No, the 10% condition is not met for both samples.
No, the Normal/large sample condition is not met for both samples.
