Answer:
The coefficient of correlation=0.5
Step-by-step explanation:
We are given that
Covariance between the variable x and y=18
Variance of x=16
Variance of y=81
We have to find the coefficient of correlation
We know that
Coefficient of correlation

Using the formula



Hence, the coefficient of correlation=0.5

Answer:
4.5
Step-by-step explanation:
This problem is set up in such a way that you take 1/10 of a number and equate it to 0.45
1/10 of x = 0.45 or
1/10 * x = 0.45 Multiply both sides by 10
1/10 * x * 10 = 0.45 * 10 Combine
x = 4.5

Answer:
Mean-39.6
Mode- 1,3,76
Median-45
MOC- 45
Step-by-step explanation
I got the mean by adding all of the numbers up and then dividing them by 13.
I got the mode because those numbers occur the most often.
I got the median by putting the numbers in order from least to greatest then picking the middle number.
I got the measure of center because there is not an outlier so you would use the median. If there was an outlier then you would use the mean.
