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?

(i)based on the distribution, do the heights appear to be reported or actually measured?
a. the height appear to be actually measured because the distribution is uniform. b. the height appear to be reported because there are disproportionately more 0s and 5s. c. the height appear to be reported because the distribution is uniform. d. the height appear to be actually measured because there are disproportionately more 0s and 5s.
(ii) what can be said about the accuracy of the results?
a. they are likely not very accurate because they appear to be reported. b. they are likely not very accurate because they appear to be actually measured. c. they are likely accurate because they appear to be actually measured. d. they are likely accurate because they appear to be reported.
