a)The F critical value for a righttailed test, for a significance level of α=0.05 is
Critical value of F=4.543 < F stat
b)Coefficient of determination r^2 = SSR/SST = 372.707/502.941 = 0.741
c)Explained variance is 74% and unexplained variance is 26%
correlation coefficient = r = 0.861
d) ŷ = b_{0} + b_{1}x
ŷ = 45.623 + 0.107 * x
Rating = 45.623 + 0.107 * Price
e)
t stat for β_{1} = 6.552 and p value = 0 < 0.05
there is a strong relation between Rating and price
t = β_{1} / Sqrt(SSE/((n2)(SS_{xx})))
t test for β_{0} = 12.569 and P value = 0 < 0.05
there is a strong relation between Rating and price
t = β_{0} / Sqrt(SSE/((n2)(SS_{yy})))
(t value and p value given in the above table)
