values of function of response Y.
Average row value of function of response:
У aver 1 = 1/4∙(0,62+0,59+0,65+0,62) = 0,62;
У aver 2 = 1/4∙(0,84+0,8+0,81+0,86) = 0,8275;
У aver 3 = 1/4∙(0,16+0,13+0,2+0,11) = 0,15;
У aver 4 = 1/4∙(0,32+0,29+0,31+0,39) = 0,3275.

Calculating of coefficients of regression equation by the
following equation:
b o = 1/4∙(0,62+0,8275+0,15+0,3275) = 0,481;
b 1 = 1/4∙(0,62-0,8275+0,15-0,3275) = -0,096;
b 2 = 1/4∙(0,62+0,8275-0,15-0,3275) = 0,242.
Then the regression equation is:
У= 0,481-0,096∙Р + 0,242∙Т.
