In what follows use any of the following tests/procedures: Regression, multiple regression, confidence intervals, one-sided T-test, or two-sided t-test.

All the procedures should be done with 5% P-value or 95% confidence interval. Some answers are approximated, choose the most appropriate answer. Open hockey data. SETUP: can on claim that players from the super elit league, on average, create more than 15 assists?

1. What test/procedure did you perform?

a. one sided t test

b. two sided t test

c. regression

d. confidence interval

2.What is the statistical interpertation?

a. since the p-value is small we are confident that the slope is not zero

b. since the p-value is small we are confident that one average is smaller than the other

c. since the p-value is too large the test is inconclusive

d. none of these

3.What is the conclusion?

a. yes, we can confirm the claim

b. No, we cannot confirm the claim

Open hockey data. SETUP: Some experts think that players in USHL league, on average, play fewer games than players in WHL league. Given the data your job is to confirm or disprove this belief.

1.What test did you perform

a. one sided t test

b. two sided t test

c. regression

d.confidence interval

2.What is the statistical interpertation?

a. since the confidence interval is too large the test is inconclusive

b.since the p-value is small we are confident that on average is smaller than the other

c. since the p-value is small we are confident that the two variables are related

d.none of thses

3.what is the conclusion

a. yes, we can confirm the belief

b. no, we cannot confirm the belief
