1.Given the linear regression equation:
y = 1.6 + 3.5x1 - 7.9x2 + 2.0x3
a.Supposed the n = 12 data points were used to construct the given regression equation above, and that the standard error for the coefficient x1 is 0.419. Construct a 90% confidence interval for the coefficient of x1.
b.(2 Points) Using the information from part (c) and 5% level of significance, test the claim that the coefficient of x1 is different from 0. What does your conclusion mean in relation to x1 predicting y?
