Question
Tests the claim that 41 > 42. Assume the samples are normally distributed, random and independent.
81 = 0.56 ; s2 = 0.5
T1 = 48.36 ; z2 = 47.38
n1 = 21 ; n2 = 38
a. Calculate the Standard Error sz-i, =
(use 3 decimal places)
b. Calculate the t-test statistic using the standard error from part a. t =
(use 2 decimal
places)
c. What are the degrees of freedom? df =
d. At a = 0.02 , Use the distribution table to find the critical values for the rejection region
te =
(use 4 decimal places)
e. What is your conclusion?
O Accept the null hypothesis and support the claim
O Fail to reject the null hypothesis and do not support the claim
O Reject the alternative hypothesis and support the claim
O Accept the alternative hypothesis and reject the claim
O Reject the null hypothesis and support the claim
