Question

Given the information in Exercise 10.27, construct a 95% confidence interval for the population mean, then reach a conclusion regarding whether μ could actually be equal to the value that has been hypothesized. How does this conclusion compare to that reached in Exercise 10.27? Why?
In exercise
For a sample of 35 items from a population for which the standard deviation is σ = 20.5, the sample mean is 458.0. At the 0.05 level of significance, test H0: μ = 450 versus H1: μ ≠ 450.
