Regression analysis

See attached file for full problem description.

A. What is the sample size?
B. Compute the value of R2.
C. Compute the multiple standard error of estimate.
D. Conduct a global test of hypothesis to determine whether any of the regression coefficients are significant. Use the .05 significance level.
E. Test the regression coefficients individually. Would you consider omitting any
variable (s)? If so, which one (s)? Use the .05 significance level.
