Mario is interested in finding out how committed individuals are to their current video streaming service. He posts a link to his survey on all of his social media platforms. Because he knows that younger people are more likely to use streaming video services than older people, he separates his population according to their age to create two groups (GROUP 1: 30 years old and younger; GROUP 2: 31 years old and older) and then randomly selects every 4th person from each group to complete his survey than older people.

Data were collected on the number of home runs (HR) hit (x-variable) and the number of games won (y-variable) by a sample of Major League Baseball teams. The following Excel output was generated from the data:  Question: Don’t worry about Ho and Ha or the 7 steps, but using only the Excel output provided, is the number of home runs hit (HR) significantly related to team wins (α = .05)? Again, don’t worry about a formal test, but make sure you explain WHY you decided the HR variable is or is not significant, statistically speaking, and what that means. [Essentially, steps 6 and 7.]
