University personnel are concerned about the sleeping habits of students and the negative impact on academic performance. In a random sample of 377 U.S. college students, 209 students reported experiencing excessive daytime sleepiness (EDS). Is there sufficient evidence to conclude that more than half of U.S. college students experience EDS? Use a 5% level of significance
STATE: What is a 90% confidence interval estimate for the proportion of all of U.S. college students who experience excessive daytime sleepiness?
PLAN: State the name of the appropriate estimation procedure (e.g. one-sample t confidence interval for estimating the mean difference)
Note: You have already described the parameter being estimated in Part A, so you don't have to repeat it here.
