In a survey, the sample consisted of 1087 adults who were parents of school-aged children. The sample was selected in a way that makes it reasonable to regard it as representative of the population of parents of school-aged children. One question on the survey asked respondents how much time (in hours) per month they spent volunteering at their children's school during the previous school year. The following summary statistics for time volunteered per month are given below. n = 1087 x = 5.5 median = 1 In USE SALT (a) What does the fact that the mean is so much larger than the median tell you about the distribution of time spent volunteering per month? O The fact that the mean is much greater than the median suggests that the distribution of times spent volunteering in the sample was negatively skewed. The fact that the mean is much less than the median suggests that the distribution of times spent volunteering in the sample was positively skewed. The fact that the mean is much greater than the median suggests that the distribution of times spent volunteering in the sample was bimodal. The fact that the mean is much less than the median suggests that the distribution of times spent volunteering in the sample was negatively skewed. The fact that the mean is much greater than the median suggests that the distribution of times spent volunteering in the sample was positively skewed.
