Answer:
6
Step-by-step explanation:
The answer is 57 4/7 or 57 full pages.
You divide 403 by 7 which equals 57 4/7 or 58(rounded up) if you are counting pages needed.
The regression equation is calculated as: ŷ = -0.99299X + 26.39918
<h3>How to solve for the regression equation</h3>
We have these data for the x axis
12 15 20 22 15 8 6 17
These are the values for the y axis
17 15 6 7 6 18 21 7
Sum of X = 115
Sum of Y = 97
Mean X = 14.375
Mean Y = 12.125
Sum of squares (SSX) = 213.875
Sum of products (SP) = -212.375
Regression Equation = ŷ = bX + a
b = SP/SSX = -212.38/213.88 = -0.99299
a = MY - bMX = 12.13 - (-0.99*14.38) = 26.39918
ŷ = -0.99299X + 26.39918
These values where inputted into a regression analysis calculator and the output is ŷ = -0.99299X + 26.39918
