Q:

The response to a question has three alternatives: A, B, and C. A sample of 120 responses provides 60 A, 23 B, and 37 C. Show the frequency and relative frequency distributions (use nearest whole number for the frequency column and 2 decimal for the relative frequency column).

Accepted Solution

A:
Answer with explanation:We know that in a frequency table we write the frequency corresponding to each of the data.The relative frequency is the ratio of the frequency to the total frequency corresponding to each entry.Here we have a total sample as: 120Also, the frequency corresponding to A is: 60Corresponding to B is: 23and corresponding to C is: 37Hence, the Frequency table is as follows:Data               Frequency  A                          60    B                           23  C                           37The relative frequency table is given by:Data               Relative Frequency            A                      60/120=0.5  B                       23/120=0.19    C                       37/120=0.31Hence, we get:Data               Relative Frequency            A                           0.5  B                           0.19  C                           0.31
