We use the t distribution to construct a confidence interval for the population mean when the underlying population standard deviationis not known. Under the assumption that the population is normally distributed, find ta/2,df for the following scenarios. (You may findit useful to reference the ttable. Round your answers to 3 decimal places.)a. A 90% confidence level and a sample of 21 observations.b. A 95% confidence level and a sample of 21 observations.c. A 90% confidence level and a sample of 13 observations.d. A 95% confidence level and a sample of 13 observations.tal2,df
