For this study, we should use | Select an a Next Compute the 90% confidence interval for the difference. Round to the nearest minute. Interpret the confidence interval in the context of the study: With 90% confidence the population mean number of minutes statistics students spend studying for their final exam is between $18 and $137 more than the population mean number of minutes statistics students spend studying for their midterm exam. With 90% confidence the mean number of minutes that the ten sampled statistics students spent studying for their final exam is between $18 and $137 more than the mean number of minutes that the ten sampled statistics students spent studying for their final exam
