Question

weights of 67 college students in kilograms in september of freshman year are provided in the accompanying data set. construct a frequency distribution. begin with a lower class limit of 40.0 kg and use a class width of 10.0 kg. does the distribution of freshman year appear to be a normal distribution? click the icon to view the freshman weights. construct the frequency distribution. weight (kg) frequency 40.0 - 49.9 2 50.0 - 59.9 24 60.0 - 69.9 23 70.0 - 79.9 11 80.0 - 89.9 3 90.0 - 99.9 4 (type your answers as integers or decimals, rounded to the nearest tenth as needed.) does the distribution appear to be a normal distribution? the frequency distribution a normal distribution because the frequencies

Explanation:

Step1: Recall normal - distribution characteristics

A normal distribution has a bell - shaped curve, with frequencies starting low, increasing to a maximum in the middle classes, and then decreasing symmetrically.

Step2: Analyze given frequencies

The frequencies are 2, 24, 23, 11, 3, 4. The frequencies increase from 2 to 24 and then decrease, but not in a perfectly symmetric way around the middle class.

Answer:

does not appear to be; do not decrease symmetrically around the middle class
