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

Male Red Blood Cell Counts Use the frequency distribution from Exercise 1 in Section 1 to construct a histogram. Using a very loose interpretation of the requirements for a normal distribution, do the red blood cell counts appear to be normally distributed? Why or why not?

Exercise 1

Constructing Frequency Distributions. In Exercise, use the indicated data and construct the frequency distribution.

Analysis of Last Digits Weights of respondents were recorded as part of the California Health Interview Survey. The last digits of weights from 50 randomly selected respondents are listed below. Construct a frequency distribution with 10 classes. Based on the distribution, do the weights appear to be reported or actually measured? What do you know about the accuracy of the results?

Solution 15BSC: The goal is to construct a histogram and to determine whether the red blood cell counts appear to be normally distributed. Step 1 of 2: From the given information, the frequency distribution for red blood cell counts (million cells / L) for males is the following: Red blood cell counts (million cells /L) Frequency 4.00 - 4.39 2 4.40 - 4.79 7 4.80 - 5.19 15 5.20 - 5.59 13 5.60 - 5.99 3
