There are 24 students enrolled in an introductory statistics class at a small university. As an in-class exercise the students were askedhow many hours of television they watch each week. Their responses, broken down by gender, are summarized in the provided table.Assume that the students enrolled in the statistics class are representative of all students at the university.3 1 12 12 0 4 10 4 5 5 2 10 10 3 = 6Female 10 3 2 10 3 2 016 1 5MaleX2 = 4Use the provided randomization distribution (based on 100 samples) to estimate the p-value for this sample for testing if this sampleprovides evidence that, on average, male students watch more television than female students at this university.10-5-3-21null -0-4-1234i

Twelve HSS students have been randomly assigned to one of three different statistics classes: one is taught by Professor Lavigne, another is taught by a monkey, and the last group has no professor and requires that students learn on their own. Here are the data: Final grade in class: Prof Lavigne: 67,74,82,55 Monkey: 43,66,52,10 No professor: 97,87,86,78 We now want to figure out if the average final grade in each class is different from one another. What kind of analysis does this require? One-way ANOVA A series of two-sample t-tests A series of one-sample t-tests None of the above What degrees of freedom are needed to answer the following question: Are average final grades statistically different in each group? 10 11 2 and 9 3 and 12 No degrees of freedom can be used
