Help please! Thank you!
A survey of major universities asked what percentage of incoming freshmen usually graduate "on time" in 4 years. Use the summary statistics given to answer the questions. Count Mean Median Sthev Min Max Range 25th %tlle 75th %tile % on time 48 65.03 67.58 10.76 44.07 89.37 45.30 60.48 76.02 a) Would you describe this distribution as symmetric or skewed? Explain. OA. QB. 00. This distribution is symmetric, because the mean and median are reasonably close to one another and the extreme values are approximately the same distance from the fences. This distribution is skewed, because the mean and median are not reasonably close to one 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 mean. b) Are there any outliers? Explain. OA. 08. 00. OD. No, because all the values in the distribution are between the fences. Yes, because the maximum value in the distribution is greater than the upper fence. Yes, because the minimum value in the distribution is less than the lower fence and the maximum value is greater than the upper fence. Yes, because the minimum value in the distribution is less than the lower fence. 0) Create a boxplot of these data. Choose the correct boxplot below.

Universities surveyed had between '2' % and E] % of students graduating on time, with the middle 50% of universities reporting between E% and Elva. The ve-number summary for the ages of 150 respondents to a survey on cell phone use is shown below. Min 01 Med 03 Max 26 28 37 4B 265 Are there any outliers in these data? Explain. What might your next steps in the analysis be? Are there any outliers in these data? Explain. The upper outlier limit is I]. The lower outlier limit is D. The El value is an outlier and is also an impossible value, given the context. (Type integers or decimals. Do not round.) What might your next steps in the analysis be? 0 A- Because the outlier is positive, it should be used when re-analyzing the data. 0 3- Because there is exactly one outlierI the data can then be used to create a boxplot. O 6- Because there is an outlier that is an impossible value. that outlier should be set aside and the data should be re-analyzed. O D- The data set does not contain any outliers, so the analysis is complete
