Question 1 2 pts

Instructions: This assignment is related to your Chapter 5 (Salkind) material. It is not timed but assignment must be submitted by the specified due. Individual assignments that are not submitted will receive a grade of “0”. This short assignment is worth 10 points.

Two Miami Heat basketball fans are arguing about whether taller players are more skilled in basketball or whether shorter players have an advantage. One friend thinks that taller players are actually better and that they're more likely to make 3 pointers. They decide to look at a correlation to test this out. They look specifically at the correlation between player's height (in inches) and the percentage of 3pointers (calculated by the number of 3 point shots made divided by the number of shots attempted--with a higher score indicating more 3 point shots made).

MIAMI HEAT PLAYER NAME 3 pointer % Height (in inches)

Bam Adebayo 8.3 81

Tyler Herro 37.8 77

Max Strus 35 77

Dru Smith 16.7 74

Now it's time to calculate the correlation coefficient (Don't panic! It's not so bad!). Here is the formula to help you out! If you're struggling with this, be sure to read over the PowerPoint from this week to help you figure out which values should go where. There is a really helpful table in that PowerPoint that you should use to organize your data. Type your answer in the box below. Round to only three decimal places!
