Hello everyone=) I have couple questions from my homework. I will be happy if someone can help me with them:
1) The points on a scatterplot lie very close to the line whose equation is y = 2 − 5x. The correlation between x and y is close to
A. 2
B. 5
C. 1
2)For a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice. The correlation is r = 0.7. If you had measured tail length in centimeters instead of millimeters, what would be the correlation?
(There are 10 millimeters in a centimeter.)
A. 0.7/10 = 0.07
B. 0.7
C. (0.7)(10) = 7

Best ResponseYou've already chosen the best response.0Ie to say if the scatterplot line was plotted, the gradient of that line would be similar to the y = 2  5x one. If the gradient of y = 25x is 5, thus gradient of scatterplot would be ~~ 5. Correlation will not change with units
