Question

the last digit of the heights of 58 statistics students were obtained as part of an experiment conducted for a class. use the following frequency distribution to construct a histogram. what can be concluded from the distribution of the digits? specifically, do the heights appear to be reported or actually measured? digit frequency 0 14 1 3 2 4 3 5 4 3 5 15 6 3 7 3 8 4 9 4 are the data reported or measured? a. the data appears to be reported. certain heights occur a disproportionate number of times. b. the data appears to be reported. the heights occur with roughly the same frequency. c. the data appears to be measured. certain heights occur a disproportionate number of times. d. the data appears to be measured. the heights occur with roughly the same frequency.

Explanation:

Step1: Analyze the frequency distribution

We observe the frequencies of the last - digits of heights. The frequencies for digits 0, 5 are much higher (14 and 15 respectively) compared to other digits (3 - 5 for the rest).

Step2: Determine if data is reported or measured

In measured data, we would expect the last - digits to occur with roughly equal frequency. Since certain digits (0 and 5) occur a disproportionate number of times, the data appears to be reported.

Answer:

A. The data appears to be reported. Certain heights occur a disproportionate number of times.
