CORRECT ANSWER✔✔- Statistically significant:
r = .65, 95% CI [.33, .97]
r = .23, 95% CI [.03, .40]
r = -.42, 95% CI [-.20, -.64]
Not Statistically Significant:
r = −.35, 95% CI [−.71, .01]
r = .25, 95% CI [−.15, .55]
r = −.41, 95% CI [−.85, .03]
Francisco is conducting an international study about a new website that is preparing to launch
worldwide. He wants to see whether men or women are more likely to be interested in the
new website so he can know which demographic to market it to.

were from Asia or North America changed how they responded to the website. Men from
Asian countries were the most interested in his website, whereas women from North
American countries were the least interested.

ANSWER✔✔- independent variable: gender
dependent variable: interest
moderator: geographic area
