Consider the following hypothesis test: H0; ,u = 18 Ha: I]! $' 18 A sample of 48 provided a sample mean 5 = 17 and a sample standard deviation 5 = 4.6. Enter negative values as negative numbers. a. Compute the value of the test statistic (to three decimal places). b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value (to two decimal places). pvalue is between and
