In what follows use any of the following tests: Regression, multiple regression, one-sided t-test, or two-sided t-test. All conclusions should be based on 5%P-value threshold.

Choose the best fitting answer.

OpenBrainsdata.SETUP:You are asked to check if heavier people have larger head circumference. Given the data, your job is to perform the appropriate statistical test or procedure.

9. What test did you perform?

a. Regression
b. Multiple regression
c. One-sided t-test
d. Two-sided t-test

10. What is theP-value?

a. 0.308149253
b. 1.9133E-17
c. 5.73019E-05
d. 0.000114604
e. None of these

11. What is the Statistical interpretation?

a. SinceP-value is very small we can conclude that weight and head circumference is related.
b. SinceP-value is too large we cannot conclude that weight and head circumference is related.
c. SinceP-value is too large we cannot conclude that the averages are different.
d. None of these.

12. What is the conclusion?

a. Test is inconclusive; thus nothing can be concluded.
b. Test is inconclusive; thus we cannot claim that weight and head sizes are related.
c. Test does not make sense, it compares "apples and oranges".
d. None of these.
