Answer:
Range = 71
Variance = 546.0
Standard Deviation = 23.4
Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
Step-by-step explanation:
We are given the following data set in the question:
33, 29, 97, 56, 26, 78, 83, 74, 65, 47, 58
Formula:
where are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 5460.18
Sorted Data Set: 26, 29, 33, 47, 56, 58, 65, 74, 78, 83, 97
Range = Maximum - Minimum
Range = 97 - 26 = 71
Based on the values, we can say that
Option A) Jersey numbers are nominal data that are just replacements for names, so the resulting statistics are meaningless.
