The following table reports counts of the number of "close friends" reported by a sample of men and a sample of women. Number of close friends 0 1 2 3 4 Total Number of male respondents 200 120 100 51 20 491 Number of female respondents 250 135 95 63 27 570 a. Is the distribution corresponding to the number of female respondents roughly symmetric, skewed to the right, skewed to the left? Explain. b. Calculate the median number of close friends for females. Round your answer to two decimal places. c. Based on the shape of the distribution (and only accounting for the number of close friends for females), do you expect the median calculated in part b. to be greater than the mean, smaller than the mean, or about the same as the mean number of close friends for men? Do not calculate the mean.
