Question

heights of statistics students were obtained by a teacher as part of an experiment conducted for the class. The last digit of those heights are listed below. Construct a frequency distribution with 10 classes. Based on the​ distribution, do the heights appear to be reported or actually​ measured? What can be said about the accuracy of the​ results? 0 0 0 0 0 0 0 0 0 1 2

Answer 1

1) B. The height appear to be reported because there are disproportionately more 0s and 5s.

2) A. They are likely not very accurate because they appear to be reported.

Explanation:

The distribution table is shown below:

Last Digit Frequency

0 9

1 1

2 1

3 3

4 1

5 11

6 1

7 0

8 3

9 1

1. Based on the distribution table, we see a very disproportionate distribution. There is a high frequency of 0's and 5's. This lays credence to the heights being reported rather than measured. As such, option B is the correct answer

B. The height appear to be reported because there are disproportionately more 0s and 5s.

2. Since the heights were reported and not measured, they are most certainly not accurate. The conclusion is that the result is not accurate. As such, option A is the correct answer

A. They are likely not very accurate because they appear to be reported.
