An evaluation thinks the execution in Graduate students' clinical skills have changed over time. A national skill test standard states that the average (M) on this test = 87, with standard deviation (SD) = 8. To test his hypothesis, the teacher takes a sample of 150 students and administered the test, yielding the following results: average 81 (SD = 6.7). Using the data and applying the Z Test, obtain the following results: Z--9.19. Taking these results into consideration, evaluate the following:
Using an alpha level = 0.05:
Identify:
a. dependent variable
b. independent variable
c. population
d. sample
e. Establish null and alternative hypotheses, both statistical and conceptual
f. Analyze the results obtained from Test Z and establish your critical Z
g. Conclude based on the established hypotheses
h. Do you consider, based on the results obtained, that this group of young people is still represented by the standards that are maintained?
