1. A sociologist is interested in whether adults with college degrees are more liberal than adults with less than a college education. This researcher takes a sample of adults with a college degree and a sample of adults with less than a college education and finds the following results about the level of liberalism measured with an interval level scale:

Adults with college degree:

x1= 53.8

s = 12.6

n1= 60

Adults with less than college

education:

x2= 51.7

s = 8.8

n2= 75

*The standard error for the difference between means is (sx-x=1.92) 12

Perform the appropriate hypothesis test to determine whether adults with college degrees aremoreliberal than adults with less than a college education with alpha = .05. Be sure to include all of the steps (i.e. state research and null hypothesis, determine critical value, determine sample statistic, state whether you reject or fail to reject null, state a concluding sentence) and show any calculations you perform.
