a. Find the critical value tc a confidence level, c= 0.99 and a sample size, n = 16

b. Find the maximum error, E, for the population mean, given c = 0.95, standard deviation, s = 5 and sample size, n = 16

c.Find the maximum error, E, for the population mean, given c = 0.99, standard deviation, s = 3 and sample size, n = 6

d. Use the TI-84 or otherwise determine the confidence interval for the population mean for a t-distribution given c = 0.90, x-bar = 12.5, s = 2.0 and n = 6()

e. Use the TI-84 or otherwise determine the confidence interval for the population mean for a t-distribution given c = 0.95, x-bar = 52.8, s = 23.4 and n = 25

f.In a random sample of 15 IPhone 11 brought in for repair, the average repair costs was $180 with a standard deviation of $14. Construct a 95% confidence interval for the population mean assuming that the costs are normally distributed.()
