Use the following results obtained from a simple linear regr

Use the following results obtained from a simple linear regression analysis with 20 observations.

= -3.5- (1.5)X
R²= 0.85 and s_b1 = 0.70
Interpret regression results and the value of the coefficient of Determination. Predict the value of Y when X is equal to 10. Calculate the correlation coefficient between Y and X. Test to determine if there is a significant relationship between the independent and dependent variable at a = 0.05 and 0.01. Perform a two-tailed test.
