A survey of major universities asked what percentage of incoming a) Would you describe this distribution as symmetric or freshmen usually graduate "on time" in 4 years. Use the summary skewed? Explain. statistics given to answer the questions. A. This distribution is symmetric, because the mean and median are reasonably close to one another and the on time quartiles are approximately the same distance from Count 48 the mean. Mean 69.31 Median 69.04 O B. This distribution is symmetric, because the mean and StdDev 10.77 median are reasonably close to one another and the Min 42.76 extreme values are approximately the same distance Max 85.29 from the fences. Range 42.53 O c. This distribution is skewed to the left, because the 25th %tile 60.26 medians is significantly less than the mean. 75th %tile 76.06 O D. This distribution is skewed to the right, because the medians is significantly greater than the mean. b) Are there any outliers? Explain. A. Yes, because the maximum value in the distribution is greater than the upper fence. O B. Yes, because the minimum value in the distribution is less than the lower fence and the maximum value is greater than the upper fence. O C. No, because all the values in the distribution are between the fences. O D. Yes, because the minimum value in the distribution is less than the lower fence. c) Create a boxplot of these data. Choose the correct boxplot below OA. OB AX 100- 90- 80- BO- HIH 60- Q 70- 60- 40- 50- 20- 10- O c. O D. Q AX 100- HITH 40
