Practice with the t distribution. An independent random sample is selected from an ap- proximately normal population with unknown standard deviation. The sample is used to construct a confidence interval of the form where i is the sample mean, C is the critical value corresponding to the desired confidence level, and s is the sample standard deviation. For each of the following sample sizes and confidence level, find the correct numerical value of C. 1. n= 7, confidence level = 80%.
