In terms of variables xi and parameters βi, write the null and alternative hypotheses for testing whether, after including Price/Square Feet(x2) in the model already, the further incorporation of the other 2 explanatory variables (x1, x3) adds any useful information for explaining pricey. Also, give the value of the F statistic and its degrees of freedom (df).
Dr. Chapman conducted an experiment in which participants watched paint dry for 30 minutes twice, once being paid $1 and once being paid $30. When comparing the samples, he calculated t = 3.57. He assumed α = .01 with df = 5, so the tcv = ±4.032. Because the calculated value was:
A. greater than the critical value, Dr. Chapman can reject the null hypothesis.
B. greater than the critical value, Dr. Chapman failed to reject the null hypothesis.
C. less than the critical value, Dr. Chapman failed to reject the null hypothesis.
D. less than the critical value, Dr. Chapman can reject the null hypothesis.
The test statistic is t = 1.34, the critical value is t = 2.011. The decision would be to: Reject the null hypothesis or Support the null hypothesis or Retain the null hypothesis or Support the alternative hypothesis.
