Consider the following hypothesis test.

H₀: = 18

H_a: 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. (Round your answer 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)

p-value is between and

c. At 0.05, what is your conclusion?

p-value is - (Select your answer -greater than or equal to 0.05, rejectgreater than 0.05, do not rejectless than or equal to 0.05, do not rejectless than 0.05, rejectequal to 0.05, do not rejectnot equal to 0.05, do not rejectItem) Ho

d. What is the rejection rule using the critical value?

Reject Ho if is - (Select your answer -greater than or equal to -2.012greater than 2.012less than or equal to -2.012less than -2.012equal to 2.012not equal to -2.012Item 5) or t is (- Select your answer -greater than or equal to 2.012greater than -2.012less than or equal to 2.012less than -2.012equal to 2.012not equal to -2.012Item 6)

What is your conclusion? (to three decimal places)
