A sample of 10 observations taken from a normally distributed population produced the following data:

(a) Test the hypothesis that H0: μ = 44 versus Ha: μ6 = 44 using α = 0.10. Draw a box plot and normal plot for this data, and comment.
(b) Find a 90% confidence interval for the population mean μ.
(c) Discuss the meanings of (a) and (b). What can we conclude?
