- In a study of 70 undergraduate students and 47 graduate students, the undergraduates had a mean reported number of hours sleeping of 6.0998 with a standard deviation of 1.1085 hrs. The graduate students had a mean of 6.6255 hours with a standard deviation of 1.8992 hours. Use StatCrunch and a significance level of 0.05 to run the t-test. What is the test statistic? What is the p-value associated with that test statistic? Give the most appropriate conclusion in context There is not evidence to reject the claim that undergraduates sleep the less than graduate students. There is evidence to support the claim that undergraduates sleep less than graduate students. We accept the claim that undergraduates sleep less than graduate students. Undergraudates sleep the same amount of time as graduate students.arrow_forward1 14 Agricultural scientists try to predict corn sed production by using annual rainfall.
