Step-by-step explanation:

From this regression output we have the MS Residual or mean squared error to be equal to 61983.1

the question requires us to find the standard error of the estimate. The standard error of the estimate can be gotten by finding the square root of the MSE.

\sqrt{61983.1}

= 248.96

the standard error of the estimate = 248.96

PLEASE HELP! I know the top part I just need the bottom!
Zolol [24]

slope  = (y2-y1)/(x2-x1)

        = (70-52)/(8-1)

    = 18/7

=2.6

point slope form

y-y1 = m(x-x1)

y-52 = 2.6(x-1)

distribute

y-52 = 2.6x-2.6

add 52 to each side

y = 2.6x+49.4

y = 2.6x +49


the initial temperature is 49.4 or about 49

and it increases about 2.6 degrees each week
