Use the t-distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal. Test Ho : HA = HB Vvs Ha : Ha # Hg using the fact that Group A has 8 cases with a mean of 125 and a standard deviation of 18 while Group B has 15 cases with a mean of 118 and a standard deviation of 14. (a) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistic = i p-value = i

Question
Use the t-distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from
random samples, and if the sample sizes are small, assume the underlying distributions are relatively normal.
Test Ho : HA = lB vs Ha : HA + HB using the fact that Group A has 8 cases with a mean of 125 and a standard deviation of 18
while Group B has 15 cases with a mean of 118 and a standard deviation of 14.
(a) Give the test statistic and the p-value.
Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places.
test statistic =
p-value =
i
