we can conclude that Amélie's cake sales are affected by the daily temperature. A. Strongly
Answer:
#1) A. -0.20; #2) C. Not
Step-by-step explanation:
The number of cakes is thought to depend on the temperature. This means that the number of cakes would be the dependent variable, y, and the temperature would be the independent variable, x.
This means in our calculator, the temperature data goes in the first list and the cake data goes in the second list.
Running a linear regression after entering the data, we get our correlation coefficient, r, as -0.1974, which rounds to -0.20.
This is not very close to -1; this means it is not a very good fit.
