Compute the value of the test statistic (to 2 decimals) 0.86 X 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.) 4 Reject Ho if t is greater than or equal to : the critical value of 1.620 (to 3 decimals). Can you conclude that the population mean is greater than 12?
