An experiment resulted in the following observations on a single dependent variable and three independent variables.
a. Estimate the regression coefficients in the model
b. Conduct an F test for a significant regression. Use a = 0.05. Use technology to find the exact p value.
c. Find the coefficient of determination.
d. Which predictor variable(s) is(are) significant in explaining the variation in the dependent variable? Conduct the appropriate hypothesis tests.
e. Construct a 95% confidence interval for the constant regression coefficient, β0. Use this interval to determine whether there is evidence to suggest the constant regression coefficient is different from 0.
