Constructing Histograms. In Exercises 9–18, construct the histograms and answer the given questions.

Analysis of Last Digits Use the frequency distribution from Exercise 20 in Section 2­2 to construct a histogram. What can you conclude from the distribution of the digits? Specifically, do the weights appear to be reported or actually measured?

Step-by-Step Solution:

Answer :

Step 1 of 1 :

From Excel

> enter the data in excel sheet

> select the dada

> go to insert

> select histogram

From the above graph we can see that the digits 0 and 5 seem to occur much more often than the other digits, so it appears that the heights were reported and not measured. This suggests that the results might not be very accurate
