Problem 16BSC

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

Female Red Blood Cell Counts Use the frequency distribution from Exercise 1 in Section 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.

Female Red Blood Cell Counts Refer to Data Set 1 in Appendix B and use the red blood cell counts (million cells/uL) for females. Begin with a lower class limit of 3.60 and use a class width of 0.40. Using a very loose interpretation of the requirements for a normal distribution, do the red blood cell counts appear to be normally distributed?

Step-by-Step Solution:
Step 1 of 3

Solution 16BSC

From the given information, the frequency distribution for red blood cell counts for females is

Red blood cell counts

Frequency

3.60 – 3.99

2

4.00 – 4.39

13

4.40 – 4.79

15

4.80 – 5.19

7

5.20 – 5.59

2

5.60 – 5.99

1

The constructed Histogram for the above frequency distribution is as follows:

Picture 29

From the above histogram, we can observe that it appear to be approximately normal distribution. Since, red blood cell counts  for females appear to be approximately normal. Since, the frequencies start from frequency 2, and then increase to a frequency 13, then increase to a high 15 and then decrease to one.
