  1. What is the value of standard error of the estimates?
  2. Test for a significant relationship by using the t test. Use α = .05
  3. Use the F test to test for a significant relationship. Use α = .05. What is your conclusion?

What I did below is that I ran the linear regression for Xi on Yi, and got the following results:

a. The value of standard error is 6.514 ( refer regression statistics table)

b. The p-value of .153 ( from the 3rd table of Coefficients) is more than the alpha = .05, meaning this variable x1 is not statistically significant

c. The p-value of 0.153 in the ANOVA table means that it is more than alpha of .05, indicating that the linear regression equation doesn't hold good - we can't use this for linear relation
