Problem 26BSC

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/μL) 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

Problem 26BSC

Step1 of 3:

We have Refer to Data Set 1 in Appendix B and use the red blood cell counts (million cells/μL) for females. Begin with a lower class limit of 3.60 and use a class width of 0.40.

Step2 of 3:

We need to check whether the red blood cell counts appear to be normally distributed by using a very loose interpretation of the requirements for a normal distribution,

Step3 of 3:

The given data can be written in terms of class interval and it is given below

 CI frequency 3.6-4 2 4-4.4 13 4.4-4.8 15 4.8-5.2 7 5.2-5.6 2 5.6-6 1

A frequency histogram is obtained by using Excel and steps are as follows

Enter the given data in Excel sheet

select data(frequency column) go to insert

choose histogram  then press ok

The red blood cell counts appear to be normally distributed, because the histogram has a rough bell shape.hence,The red blood cell counts appear to be normally distributed.
