- Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.arrow_forwardYou intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 8. While it is an uncommon confidence level, find the critical value that corresponds to a confidence level of 93.5%.arrow_forwardhi, could you please help me with solving this problem? thank youarrow_forward
