Weights of 67 college students in kilograms in September of freshman year are provided in the accompanying data set. Construct a frequency distribution.

a) The number of classes in the frequency distribution is 6.
b) The class width is 5 kg.
c) The upper class limit for the first class is 45 kg.
d) The frequency of the class 45-50 kg is 8.

Answer :

Final answer:

A frequency distribution begins with a class of 40-45kg, followed by a 45-50kg class with a frequency of 8 students, moving up in 5kg increments with a total of 6 classes.

Explanation:

The subject is looking to construct a frequency distribution for a set of college students' weights with the following conditions: the number of classes is 6, the class width is 5kg, the upper class limit for the first class is 45kg, and the frequency of the class 45-50kg is 8.

Following the given criteria:

  1. First Class: 40-45kg
  2. Second Class: 45-50kg with a frequency of 8 students.

Given that we need six classes and a class width of 5kg each, the remaining classes will be 50-55kg, 55-60kg, 60-65kg, and 65-70 kg. Note that we do not have the data to fill in the frequencies for these classes, except for the specified class of 45-50kg.
