A group of 29 statistics students were collecting data for a project in class. One of the variables of interest was the day of the month each student was born. Summary statistics for the data are shown. 1 1 Day of the Month Born 6 7 2 3 4 11 13 13 13 14 19 20 22 23 23 Mean: 13.97 Standard deviation: 7.98 15 15 24 25 8 8 16 16 27 27 11 18 Is this distribution of "Day of the Month Born" for this statistics class approximately Normal? Justify your answer using the 68-95-99.7 rule. OYes, there is clear symmetry in the data. OYes, the data distinctly follow the 68-95-99.7 rule. OYes, the number of students in this sample is large. No, the data set does not have any possible outliers. O No, the data do not follow the 68-95-99.7 rule, even though the histogram shows symmetry.
