A survey of Ohio University students was conducted to determine if there was a particular 'Green' that was desired by students to live on. A sample of 210 students responses are reproduced below. Do students prefer a particular 'Green'? Use critical value = 5.99. West green:70 south green:50 East Green:90 Q1: What are the expected values? Q2: What is the calculated chi-squared value? Q3: Was there a significant preference for where students live? A. Yes B. No A local sports bar wanted to determine whether Ohio University students prefer a particular type of food in their establishment. A sample of 100 students responses are reproduced below. Do students prefer a particular type of bar food? Use critical value = 7.82. Nachos:18 pizza:22 chicken wings:20 cheese sticks:40 Q4: What are the expected values? Q5: What is the calculated chi-squared value? Q6: Was there a significant preference for what students eat in a sports bar? A. Yes B. No The following data comes from \"The Impact of AIDS on Gender Differences in Willingness to Engage in Casual Sex\" by Russell Clark, Journal of Applied Social Psychology, Vol. 20, No.9, pp.771-782. In this study researchers were interested in gender differences in willingness to engage in casual sex. Both males and females were approached by opposite sex confederates and asked one of the three questions: \"I have been noticing you around campus. I find you to be very attractive.\" Then the confederate asked one of these three questions: \"Would you go out with me tonight?\" \"Would you come over to my apartment tonight?\" \"Would you go to bed with me tonight?\" The type of question was randomly determined for each request. Test for a relationship between gender and compliance with each request. Interpret your findings. The results for the first two questions are as follows: Date Yes: male: Female 11 7 No: 5 9 Q7: What are the expected values for 'male-yes' and 'female-yes' (they should be the same)? Q8: What are the expected values for 'male-no' and 'female-no' (they should be the same)? Q9: What is the calculated chi-squared value? Q10: Using a critical value of 3.84, was there a significant relationship between gender and compliance? A. Yes B. No Apartment Yes No Male: 8 8 Female: 2 14 Q11: What are the expected values for 'male-yes' and 'female-yes' (they should be the same)? Q12: What are the expected values for 'male-no' and 'female-no' (they should be the same)? Q13: What is the calculated chi-squared value? Q14: Using a critical value of 3.84, was there a significant relationship between gender and compliance? A. Yes B. No Q15: Which of the following data organization schemes is useful in showing changes in data relationships over time? A. bar graph B. pictogram C. pie chart D. line graph E. scatterplot F. none of the above Q16: Which of the following is/are necessary for properly displaying a statistical plot, picture, or graph? A. a title B. a source C. proper labeling of the axes D. proper labeling/representation of the pie segments, bars, etc. E. All of the above Q17: A pie chart would be most appropriate with which of the following statistical tests? A. chi-square goodness-of-fit B. chi-square test for independence C. correlation
