Open Brainsdata IN THE COMMENTS.Since females are on average smaller than males, some people believe that female brains should be smaller as well (smaller volume).

OpenBrainsdata IN THE COMMENTS.Since females are on average smaller than males, some people believe that female brains should be smaller as well (smaller volume). Given the data, the task is to perform the appropriate statistical test or procedure and help them decide.

5. What test did you perform?

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

6. What is theP-value?

a. 0.115912154
b. 0.057956077
c. 7.38553E-20
d. 3.69277E-20
e. None of these

7. What is the Statistical interpretation?

a. SinceP-value is very small we can conclude that female brain is smaller in volume.
b. SinceP-value is too large we cannot conclude that male and female brains have different volume.
c. SinceP-value is too large we cannot conclude that female brain is smaller in volume.
d. None of these.

8. What is the conclusion?

a. Test is inconclusive; thus nothing can be concluded.
b. Test is inconclusive; thus we cannot claim that the brain volumes are different.
c. Test is inconclusive; thus we cannot claim that there is a correlation between brain volume and gender.
d. None of these.
