Write a hypothesis that you might test to compare two or more samples in your example. Indicate which hypothesis test you would use and the samples you would select. To support your choice of test include a brief discussion of the level of measurement, the number of samples involved, and whether the samples are related or independent[Minimum word count for the initial discussion post is 100 - 500 words]
Please use the following outline -
1. Hypothesis that you want to test:
2. Indicate which tail test you are using:
3. Discuss the samples you have selected:
4. Number of samples involved:
5. Discussion of whether the samples are related or independent:
A graphical presentation may accomplish ALL BUT which of the following objectives? Illustrate the amount of variation in the data.

Please perform a hypothesis test using a .05 significance level on the following information. Next please perform a regression analysis as well as providing a scattered diagram.
Give the Z- score cutoff (or cutoffs) on the comparison distribution at which the null hypothesis should be rejected
Determine z score corresponding to minimum height requirement and determine z score corresponding to maximum height requirement.
