Consider the following hypothesis test:

H:=18

H:18

A sample of 48 provided a sample mean x=17 and a sample standard deviation s=4.7.

Enter negative values as negative numbers.

a.Compute the value of the test statistic (to three decimal places).

b.Use the distribution table (Table 2 in Appendix B) to compute a range for the -value (to two decimal places).
