The one-sample t statistic from a sample of n=25 observations for the two-sided test of
H0: u = 64
Ha: u ? 64
has the value t = -1.12
(a) Find the P-value for this testing using Table B (t distribution critical values chart). What conclusion would you draw at the 5% significance level? At the 1% significance level?
(b) Redo part (a) using an alternative hypothesis of Ha: u < 64.
