Consider a random sample of seven college students at a particular university (n = 7), where H, is the number of hours of study on the day prior to the final exam. H, (3,3,5,6,7,8,10) = Suppose that a professor claims that the typical college student studies more than 4 hours on the day prior to the final exam. Assume that the population distribution for hours of study is normally distributed. A. B. C. What is the null hypothesis? What is the alternative hypothesis? Can you reject the null hypothesis at the 10-percent level of significance? Can you reject the null hypothesis at the 5-percent level of significance? Use the critical value approach. You can use R to look up critical values, 1 but you must show all of your calculations and explain. Use R, however, to check your work. What is the 95-percent confidence interval for hours of study? Provide a written interpretation of what your 95-percent confidence interval implies.
