Answer

Explanation:

Step1: Analyze the frequency - distribution data

The class intervals are A: 39 - 44 (frequency = 1), B: 45 - 50 (frequency = 2), C: 51 - 55 (frequency = 6), D: 57 - 62 (frequency = 14), E: 63 - 68 (frequency = 5), F: 69 - 74 (frequency = 1), G: 75 - 80 (frequency = 2).

Step2: Match with the histograms

In a normal - distribution histogram, the data is symmetric about the center. The highest frequency is in the middle class (D: 57 - 62 with frequency 14) and the frequencies decrease on either side. Histogram C matches this pattern.

Step3: Determine the distribution type

The data has a single peak in the middle class (D) and the frequencies decrease on both sides, which is characteristic of a normal distribution.

Answer:

Choose the correct histogram below: C. Do the data appear to have a distribution that is approximately normal? A. Yes, it is approximately normal.
