Question 11 A sample of adults was asked to indicate the amount of money, in dollars, they would be willing to spend on a wedding gift. When a histogram was constructed based on the responses given by each adult, most of the dollar amounts were on the larger side, with only a few dollar amounts on the smaller side. Two measures of center were calculated for this sample: $150 and $279. One of these measures is the mean, and the other is the median. Which measure must be the mean? The mean is $279 because the distribution of dollar amounts would be skewed to the left. The mean is $279 because the distribution of dollar amounts would be skewed to the right. The mean is $150 because the distribution of dollar amounts would be skewed to the left. The mean is $150 because the distribution of dollar amounts would be skewed to the right.
