Listed below are the ages (in years) of Olympic marathon winners at the time of their victories. Use these ages to construct a frequency distribution. Use a class width of 5 years and begin with a lower-class limit of 20 years. Do the ages appear to have a normal distribution? Give reason.Data Set (Ages of Olympic Marathon Winners):23, 28, 32, 30, 29, 27, 31, 34, 26, 33, 25, 30, 35, 24, 28, 29, 27, 31, 33, 26, 36, 34, 30, 32, 29, 28, 37, 25, 26, 35\text{23, 28, 32, 30, 29, 27, 31, 34, 26, 33, 25, 30, 35, 24, 28, 29, 27, 31, 33, 26, 36, 34, 30, 32, 29, 28, 37, 25, 26, 35}

Yes, the distribution is approximately normal because it is symmetric, unimodal, and bell-shaped.

No, the distribution is not normal because the values are heavily skewed towards younger ages.

No, the distribution is not normal because the frequencies are nearly equal across all class intervals.

It cannot be determined without plotting a histogram.
