Directions: Please provide all answers using complete sentences. You are required to show your work on any item that involves calculations.

1.    The following data represent the number of points scored per non-conference game during the 2016 football season by the Texas Longhorns and the Texas A & M Aggies:

Texas Longhorns: 50, 41, 43
Texas A & M Aggies: 31, 67, 52, 23, 28

Please answer the following questions (a-e below are worth 1 point each):

a.    What are the M and SD points per game for the Texas Longhorns?
b.    What are the M and SD points per game for the Texas A & M Aggies?
c.    Z-score for Texas’s 50 point game
d.    Z-score for Texas A & M’s 67 point game
e.    What is the specific statistical analysis that should be used if one wished to compare these two means?
2.    Please provide a detailed description of an original example (i.e., something not discussed in class or the textbook) of a situation in which a paired samples t-test would be most appropriate.

3.    A researcher asks a sample of male gym goers to rate from 1 (No importance) to 5 (Extreme importance) the extent to which each individual values overall size and symmetry of his musculature (this is henceforth referred to as “Body size and symmetry”). Also, based on subject self-report, the researchers categorize men either as “steroid users” or “non- users.” When the researchers compare the Body size and symmetry scores of the steroid user (M = 4.27, SD = .82) and non-user (M = 3.15, SD = .67) groups, their output is: t(28) = 2.43, p = .02. Please provide the following information (a-d worth 1 point each):

a. A specific interpretation of this analysis that makes explicit reference to the variables involved.
b. Identification of the specific statistical test used.
c. N for the study, as well as the a priori p-value.
d. An explicit statement about the status of the null after this result.
