7. [-I7 Points] 0/2 Submissions Used A survey of major universities asked what percent of incoming freshmen usually graduate "on time" in 4 years. Use the summary statistics below to answer the questions. Count Mean Me n Std. Dev. Range Min Max Q1 48 58.49 Q3 75.79 (a) Would you describe this distribution as symmetric or skewed? O This distribution is skewed because the standard deviation is different from the IQR. (b) According to the IQR rule, are there any outliers? 0 Yes, there is at least one outlier on the high end. 0 Yes, there is at least one outlier on the low end and on the high end. 0 Yes, there is at least one outlier on the low end. No, there are no outliers as dened by either mathematical rule. O This distribution is skewed, because the mean and median are not very close to one another and the quartiles are not exactly the same distance from the median. O This distribution is symmetric, because all the values fall inside the fences and the quartiles are approximately the same distance from the median. PRACTICE ANOTHER This distribution is symmetric, because the mean and median are reasonably close to one another and the quartiles are approximately the same distance from the median. (c) Identify the correct boxplot for this data set: 0 (d) Enter the missing values: The middle 50% of on-time graduation rates lie between 58.58 and 75.69
