Question

A data set whose original x values ranged from 28 through 49 was used to generate a regression equation of ŷ = 2.9x – 34.7. Use the regression equation to predict the value of y when x=44.260.492.990.6Meaningless result

Answer 1

92.9

Step-by-step explanation

To find the value of y when x = 44, we have to substitute the value of x in the regression equation and solve,

`y=2.9\cdot44-34.7=127.6-34.7=92.9`

Hence, the value of y when x = 44 is 92.9.
