Given:

A data set whose original x values ranged from 41 through 78 was used to generate a regression equation:


y=5.3x-21.9

We will use the equation to predict the value of y when x = 56

So, substitute x = 56 into the given equation:


y=5.3*56-21.9=296.8-21.9=274.9

So, the answer will be 274.9
