Chapter 9, Problem 72(choose chapter or problem)
The one-sample t statistic from a sample of n = 25 observations for the two-sided test of
\(\begin{array}{l} H_{0}: \mu=64 \\ H_{a}: \mu \neq 64 \end{array}\)
has the value t = -1.12.
(a) Find the P-value for this test using Table B or technology. What conclusion would you draw at the 5% significance level? At the 1% significance level?
(b) Redo part (a) using an alternative hypothesis of \(H_{a}: \mu<64\).

QUESTION:
The one-sample t statistic from a sample of n = 25 observations for the two-sided test of
\(\begin{array}{l} H_{0}: \mu=64 \\ H_{a}: \mu \neq 64 \end{array}\)
has the value t = -1.12.
(a) Find the P-value for this test using Table B or technology. What conclusion would you draw at the 5% significance level? At the 1% significance level?
(b) Redo part (a) using an alternative hypothesis of \(H_{a}: \mu<64\).
ANSWER:Step 1 of 3
Given hypothesis:
Null hypothesis: \(H_{o}: \mu=64\)
Alternative hypothesis: \(H_{a}: \mu \neq 64\)
Number of samples: n = 25
T - value =-1.12
