Problem 11BSC

Normal Distributions. Answer the given questions which are related to normal distributions.

Identifying the Distribution Using a reasonably strict interpretation of the relevant criteria, does the frequency distribution given in Exercise appear to have a normal distribution? Explain.

Exercise

identify the class width, class midpoints, and class boundaries for the given frequency distribution. The frequency distributions are based on real data from Appendix B.

Step-by-Step Solution:
Step 1 of 3

Problem 11BSC

Step1 of 3:

We have ,

 CI frequency 20-29 27 30-39 34 40-49 13 50-59 2 60-69 4 70-79 1 80-89 1

Step2 of 3:

We need to Using a reasonably strict interpretation of the relevant criteria, does the frequency distribution given in Exercise appear to have a normal distribution? Explain.

Step3 of 3:

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

From the above graph we can say that the given frequency distribution is skewed right and The frequency distribution does not appear to be normal because the frequencies do not start off low, nor do they peak at around one of the middle classes.
