Suppose you would like to construct a two-sided 95% confidence interval on the population mean, u, of a normal population. To construct this interval, you gather a random sample of eight observations from the population, and from this sample you compute x = 9 and s = 0.7. If you the confidence interval will be of the form (a, b), what is the value of b (i.e., the upper bound of your interval)? QUESTION 4
