Answer 1

What is the mean value of Y?
To find the mean value of Y, we need to sum up all the values of Y and divide by the total number of observations.

Sum of Y = $2,207.92 + $671.68 + $1,395.33 + $1,962.74 + $2,250.40 + $2,032.22 + $2,362.16 = $12,882.45

Total number of observations = 7

Mean value of Y = Sum of Y / Total number of observations = $12,882.45 / 7 = $1,840.35

Therefore, the mean value of Y is $1,840.35.
