Question

Consider the following hypothesis test: H0: ? = 18 Ha: ? ? 18 A sample of 48 provided a sample mean x? = 17 and a sample standard deviation s = 4.5. If requires, round your answers to two decimal places. Enter negative values as negative numbers. a. Compute the value of the test statistic. -1.54 b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value. p-value is between .20 and .10 c. At ? = 0.05, what is your conclusion? p-value is greater than 0.05, do not reject H0 d. What is the rejection rule using the critical value? Reject H0 if t is greater than 2.012 or t is less than -2.012 What is your conclusion? t = 18; do not reject H0

A sample of 48 provided a sample mean x? = 17 and a sample standard deviation s = 4.5.
If requires, round your answers to two decimal places. Enter negative values as negative numbers.
a. Compute the value of the test statistic.
-1.54
b. Use the t distribution table (Table 2 in Appendix B) to compute a range for the p-value.
p-value is between .20 and .10
c. At ? = 0.05, what is your conclusion?
p-value is greater than 0.05, do not reject H0
d. What is the rejection rule using the critical value?
Reject H0 if t is greater than 2.012 or t is less than -2.012
What is your conclusion?
t = 18; do not reject H0
