A simple linear least squares regression of the heights (in feet) of a building on the number of stories in the building was performed using a random sample of 30 buildings. The associated ANOVA F statistic was 5.60. What is the P-value associated with this ANOVA F test? a.) greater than 0.10 b.) between 0.001 and 0.01 c.) between 0.01 and 0.025 d.) between 0.05 and 0.10 e.) between 0.025 and 0.05 f.) less than 0.001

A least-squares simple linear regression model was fit predicting duration (in minutes) of a dive from depth of the dive (in meters) from a sample of 45 penguins' diving depths and times. Calculate the F-statistic for the regression by filling in the ANOVA table. SS df MS F-statistic Regression Residual 1628.4056 Total 367385.9237

In least squares regression, which of the following is not a required assumption about the error term ε?

5. In least squares regression, which of the following is not a required assumption about the error term ε? a. The expected value of the error term is one. b. The variance of the error term is the same for all values of x. c. The values of the error term are independent. d. The error term is normally distributed. 7. Larger values of r2(R2) imply that the observations are more closely grouped about the a. Average value...
