For this study, we should use t-interval for a population mean z-interval for a population proportion t-interval for the difference between two independent population means z-interval for the difference between two population proportions t-interval for the difference between two dependent population means Part 2 of 3 Come up with the 90% confidence interval for the difference. Round your answers to four decimal places and present your answers as proportions rather than percents.
