HW 3 Practice Problems: Question 11-12: The crosstabs you just did for Question 10 aren't valid due to the bad cells. To correct this, recode the variable for the type of drinker students consider themselves (the one you just used in the crosstabs for Question 10) as follows: 1 = non and social drinkers2 = moderate, heavy, and problem drinkers Call the new variable TYPE2. Label the new variable as shown in the prior sentence. (Note: you should have the same number of missing as in the original variable.) How many respondents are in the "moderate, heavy, and problem drinkers" category?

HW 3 Practice Problems: Questions 13-16: Use the variables BINGE and TYPE2 to test the null hypothesis "There is no association between binge drinking and the type of drinker a student considers her/himself to be". Use the output to answer Questions 13-16. Based on the p-value, is there an association between binge drinking and what type of drinker a student considers her/himself?

HW 3 Practice Problems: Questions 13-16: Use the variables BINGE and TYPE2 to test the null hypothesis "There is no association between binge drinking and the type of drinker a student considers her/himself to be". Use the output to answer Questions 13-16. Which group is more likely to be binge drinkers? a. non and social drinkers b. moderate, heavy, and problem drinkers c. neither

no

HW 3 Practice Problems: Questions 17-18: Define a new variable ENROLLED as follows:1 = enrolled in less than or equal to 15 credit hours per week2 = enrolled in 16 or more credit hours per week Use this new variable to test the null hypothesis "There is no association between gender and hours enrolled". Use the output of the test procedure to answer Questions 17-19. Based on the p-value, is there an association between gender and hours enrolled?

0.824

HW 3 Practice Problems: Questions 17-18: Define a new variable ENROLLED as follows:1 = enrolled in less than or equal to 15 credit hours per week2 = enrolled in 16 or more credit hours per week Use this new variable to test the null hypothesis "There is no association between gender and hours enrolled". Use the output of the test procedure to answer Questions 17-19. What is the p-value. Please round your answer to 3 decimal places.

5

HW 3 Practice Problems: Run the appropriate test for the hypothesis "There is no association between binge drinking (use the variable BINGE) and the type of drinker a student considers him/herself to be." How many "bad" cells are there?

0.33

HW 3 Practice Problems: The null hypothesis is "IU students that are at least 22 years old have mean GPAs that are less than or equal to IU students that are younger than 22". Run the appropriate test for this hypothesis. What is the p-value? Please round your answer to 2 decimal places.

b

HW 3 Practice Problems: Use the FRDRINK variable to create a new variable FRDRINK2 as follows:1 = FRDRINK values of 1,2,3 (label this category "disagree or neutral")2 = FRDRINK values of 4,5 (label this category "agree") You should have the same number missing in FRDRINK2 and FRDRINK. Use the new variable FRDRINK2 and the variable BINGE to test the null hypothesis "There is no association between binge drinking and how students feel about the statement 'For my friends, drinking is a part of having a good time'". Ignore the 1 bad cell and assume that the output is valid. The respondents in which category of FRDRINK2 are more likely to be binge drinkers? a. disagree or neutral b. agree c. neither
