Larger scores are better. A t value of 2.50 was calculated and an α level of .05 adopted. Which conclusion is appropriate with a 2-tailed test?If df = 4, Cats are significantly better than DogsIf df = 9, Dogs are not significantly different from CatsIf df = 5, Dogs are significantly better than CatsIf df = 10, Dogs are significantly better than CatsQuestion 3:A department chair in an academic department wanted to know if there was a difference between spring and fall enrollment in his department. The department offered the same six courses both semesters. What test should he conduct to determine if there is a significant difference in the enrollment between the semesters? Write up the results and determine what do the results mean? Here is the data set:SpringFall873090355640484539505055

Question 4 - Hypothesis TestingPromptBased on a recent study of college students, the average student loan debt amount is $4000. Is the mean student loan debt higher at StatCrunchU? Include each of the following in your response. (see concepts in Units 7 & 8 – Modules 17-23)State your hypotheses in symbolic form and in words.Verify that normality conditions are met. Which test are you using? Why?Use StatCrunch to conduct the hypothesis test. Copy and paste the results (the StatCrunch output window) into your response.Give your P-value and interpret its meaning.State a conclusion that answers the research question. Use a significance level of 5%.StatCrunch ResourcesHere is a PDF document with all StatCrunch directionsHow & What to Turn InSubmit your answers to the prompt above.
