So what do we know?
We know that by the Central Limit Theorem,
as n, the distribution of the sample mean
becomes Normal, with centre and standard
deviation /n.
This happens reg

1. Identify the explanatory and response variables, and explain your reasoning.
The explanatory variable in this study would be the gender differences. That is male
