Chapter , Problem 26(choose chapter or problem)
We have five observations drawn independently from a normal distribution with unknown mean t-t and unknown variance (j 2 . (a) Estimate t-t and (j 2 if the observation values are 8.47, 10.91, 1 0.87, 9.46, 1 0.40. (b) Use the t-distribution tables to test the hypothesis t-t = 9 at the 95% significance level, using the estimates of part (a).
