T test for independent groups and dependent groups (Twogroup designs)
1. An LU professor is interested in whether there is a difference between undergraduate students and graduate students in the amount of time spent praying each day. The professor gathers information from random samples of undergraduate and graduate students on the LU campus. The amount of time praying is normally distributed and is measured on an interval/ratio scale.

a. What statistical test should be used to analyze the data?
b. Is this a one or two tailed test?
c. Identify H0 and Ha for this study.
d. Conduct the appropriate analysis. Should H0 be rejected?

University of Phoenix does NOT give us the School Subject. We are not associated with any textbook, etc. so we don't know what you have in that area.
Please look to the red menu, upperleft, and select one of the School Subjects listed there.
