Use the summary statistics below to answer the Count Mean Median Std. Dev. Range -t-6759 48 67.74 1 | 43.55-43.95-t- 87.5- t-58.2976.35 10.45 (a) Would you describe this distribution as symmetric or skewed? This distribution is skewed because the standard deviation is different from the IQR. O This distribution is symmetric, because all the values fall inside the fences and the quartles are O This distribution is symmetric, because median are the mean and median are reasonably close to one another and the quartiles are approximately the same distance from the median. This distribution is skewed, because the mean and median are not very dose to one another and the quartiles are not e actly the same distance from the medan (b) According to the IQR rule, are there any outliers? Yes, there is at least one outlier on the low end. O No, there are no outliers as defined by either mathematical rule. Yes, there is at least one outlier on the low end and on the high end Yes, there is at least one outlier on the high end. (c) Identify the correct boxplot for this data set:
