An LU professor is interested in whether there is difference between undergraduate students as well as graduate students in amount of time spent praying each and every day. The professor collects 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 interval/ratio scale.
