Answer required:  Critical value. 

Consider the following hypothesis test:
Họ: µ< 12
Ha: 4> 12
A sample of 25 provided a sample mean = 14 and a sample standard deviation 8 = 4.32.
a. Compute the value of the test statistic (to 2 decimals).
2.31
b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value.
The p-value is between 0.01 and 0.025
c. At a = 0.05, what is your conclusion?
Reject null hypothesis
d. What is the rejection rule using the critical value? (Use a = 0.05.)
Reject Ho ift is greater than or equal to
the critical value of 1.644
(to 3 decimals).
Can you conclude that the population mean is greater than 12?
Yes
