Question

7. A survey of first-year and second-year students at a large university asked if students were satisfied with college life. We are interested in whether there is a difference between first and second-year students with respect to this question. You performed a hypothesis test and found there was no evidence of a difference between first and second-year students in response to this question. You based th on a test using alpha -0.01. Would you have made the same decision at alpha -0.05? Explain. (Hint state the null and alternative hypotheses). 3 points

Answer 1

A null hypothesis is a hypothesis that says there is no statistical significance between the two variables. It is usually the hypothesis a researcher or experimenter will try to disprove or discredit. Analternative hypothesis is one that states there is a statistically significant relationship between two variables.

Null: Life is same for both year students

Alt: Life is not same for both year students

In test, there was no evidence for difference, so it means we could not reject null

This means p > alpha of 0.01

So, at alpha 0.05 we are not sure

if p valye > 0.05 same result

if p < 0.05 but greater than 0.01 we have different result
