In a survey, 39% of a randomly selected sample of n = 935 American adults said that they do not get enough sleep each night. The margin of error for the 95% confidence level was reported to be 3.4%. (a) Use the survey information to create a 95% confidence interval for the percentage that feels they don't get enough sleep every night. % to % Write a sentence that interprets this interval. Specify the population. With night. % confidence, we can say that in the population of American adults between ' % and % would say they don't get enough sleep each (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? No, the population the sample comes from may not be representative of college students, fulfilling the Fundamental Rule for Using Data For Inference. No, the population the sample comes from may not be representative of college students, violating the Fundamental Rule for Using Data For Inference.
