Question details

In a survey of introductory statistics students, an instructor asked her students to report how many Facebook friends they had. Suppose that the intent is to study whether there is an association between number of Facebook friends and a persons sex. Use the difference between the sample means as your statistic. The standard deviation found using a randomization-based test of whether the average number of Facebook friends men have is different from that of women is 97.89, and the p-value is 0.0520 Sample Sample Sample Sample size 35 13 mean median 594.30 405.60 SD 309.80 228.40 Women 532 Men 485 Your answer is partially correct. Try again. Use the 2SD method and the information given to find a 95% confidence interval for the difference in average number of Facebook friends that men have and that women have. (Round your answers to 2 decimal places, e.g. 5.71.) 7.08 385.5
