Question

Question2 We are interested in studying the average amount of sleep that college students get each night. Suppose we randomly select 12 students from a local college, and each student reports how many hours of sleep they got last night. 6.0 7.6 7.2 2.1 7.9 6.2 7.7 8.9 7.4 6.0 6.6 e. Suppose we would like to conduct a classical inference test to see whether the mean is 8 hours of sleep per night. If the conditions are met for classical inference, find the p-value. If they are not met, explain why they fail f. If you found the p-value in the previous part, interpret your results informally. Otherwise, leave this part blank. g. Suppose we would like to make a bootstrap confidence interval for the median (not the mean). Determine whether we can make a valid bootstrap confidence interval. If so, find and interpret the interval. If not, explain why not.

Explanation / Answer

e)

One-Sample T: C1

Test of = 8 vs 8

Variable   N   Mean StDev SE Mean      95% CI          T      P
C1        12 6.217 2.353    0.679 (4.721, 7.712) -2.63 0.024

p-value= 0.024 < 0.05

hence reject the nul
