Answer:
Problem 1 -Rectangle
Problem 2- Not sure how to describe, but here's an approximate picture
Answer:
2/52
Step-by-step explanation:
If he took one ace out of 52 cards then it would have been 4/52
but as he's taking 2 aces out of 52 cards it is 2/52
Answer:
We have a strong negative relationship between the variables.
Step-by-step explanation:
Given two random variables X and Y, it is possible to calculate the covariance as Cov(X, Y) = E(XY)-E(X)E(Y). We have E(X)=5, E(Y)=6 and E(XY)=21. Therefore Cov(X,Y)=21-(5)(6)=21-30=-9. On the other hand, we know that the correlation of X and Y is the number defined by
and because in this particular case we have V(X)=9 and V(Y)=10, we have
= -0.9487. Therefore, we have a strong negative relationship between the variables.
The <u>correct answer</u> is:
<span>c) Each point in the data set is near the regression line.
Explanation:
A best fit regression line is the line that most closely approximates the data. This means that the line must be near most of, if not all, of the points of the data set.
If this truly is the line of best fit, the points of the data will be near the line.</span>
