In a 1997 survey done by the Marist College Institute for Public Opinion, 36% of a randomly selected sample of n = 935 American adults said that they do not get enough sleep each night (Source: http://www.mipo.marist.edu). The margin of error was reported to be 3.5%.
a. Use the survey information to create a 95% confidence interval for the percentage that feels they don’t get enough sleep every night. Write a sentence that interprets this interval. Specify the population.
b. Do you think this sample could be used to estimate the percentage of college students who think they don’t get enough sleep each night? Why or why not?
