Question
A friends the person has on a social m Men Women 0 to 50 17 45 (A) 0.0125 (B) 0.0265 X (C) A r-test for the slope of the regression line (D) A chi-square goodness-of-fit test 36 (E) A chi-square test of independence (C))0.0471 0.0506 (E) 0.1012 51 to 100 82 73 Which of the following procedures is the most appropriate for investigating whether an association exists between gender and the number of friends a person has on a social media Web site? t (A) A matched-pairs t-test for a mean difference (B) A two-sample t-test for the difference between means Number of Friends 101 to 150 73 98 151 to 200 201 or more 56 42 87 75 6. A test of the hypotheses Ho := 0 versus H₂> 0 was conducted using a sample of size 7. The test statistic was t = 1.935. Which of the following is closest to the p-value of the test? bin 7. From a random sample of 50 people, sitting pulse rates and standing pulse rates were measured for each person. A coin was flipped to determine whether the sitting or the standing pulse rate would be measured first. Let sitting represent the mean sitting pulse rate in the population, standing represent the mean standing pulse rate in the population, and a represent the mean of the differences between the sitting and standing
