Unit 4 Discussion - Am I Normal?

I am 5'2

Instructions:

The average height for all males is 69.3 inches with a standard deviation of 2.8 inches. For females, the average height is 64 inches and the standard deviation is 2.8.These are population values. For this week's discussion, you will calculate a z-score based on your own height and determine whether your score is within the 95% normal range or if it is out of that range and considered unusual.

• Measure your height as precisely as possible to a tenth of an inch. For example, 5'2 " would be 62.3 inches tall.
• Calculate the z-score based on population values for males or females.Use the formula:z= (x-)/ where x is your height in inches.
• Calculate the normal range by creating the interval that is within 2 standard deviations of the population mean.Multiply the population standard deviation by 2 and then add/subtract from the population mean.

In your discussion post, include the following, based on your calculations.

• Is your height within the normal range?Is this what you expected?
• Would your height be considered unusual?Why or why not.
• Have you encountered any challenges based on your height?For example, someone who is shorter or taller may have a difficult time finding pants that are an appropriate length.
• How is the concept of normality used in your field?For example, a patient's blood pressure is compared to a normal range of values and a financial planner may check the "average" return of a stock.
• How does knowing what is usual help people and corporations and government organizations plan?For example, how do airplane manufacturers use the normal height to design aircraft seating?
