Question:

Refer to Data Set 1 in Appendix B and use the red blood cell counts (million cells/μL) for males. Begin with a lower class limit of 4.00 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?
