Question

We use the t distribution for the statistical inference of the population mean when the underlying population standard deviation is not known. Under the assumption that the population is normally distributed, find T_a/2, df for the following scenarios. Use Table 2. a. A 99% confidence level and a sample of 24 observations. b. A 90% confidence level and a sample of 24 observations. c. A 99% confidence level and a sample of 20 observations. d. A 90% confidence level and a sample of 20 observations.
