Problem 16BSC

Female Red Blood Cell Counts Use the frequency distribution from Exercise 26 in Section 2-2 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?

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:

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.
