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 appear to be a normal distribution? click the icon to view the freshman weights. construct the frequency distribution. (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 is very likely not a normal distribution because the frequencies are all exactly the same. start high and steadily decrease. are all roughly the same. start low, increase, and then decrease, and are roughly symmetric. start low, increase, and then decrease, but are not roughly symmetric. start high, decrease, and then increase, and are roughly symmetric. start low and steadily increase.

Explanation:

Step1: Recall normal - distribution properties

A normal distribution has frequencies that start low, increase, then decrease, and are roughly symmetric.

Step2: Analyze given frequencies

The frequencies for weight intervals are 2, 24, 23, 11, 3, 4. They start low (2), increase (24, 23), then decrease (11, 3, 4), but are not roughly symmetric.

Answer:

The frequency distribution is very likely not a normal distribution because the frequencies start low, increase, and then decrease, but are not roughly symmetric.
