A software firm collected data for a sample of30computer programmers. A regression analysis can be used to determine if annual salary ($1000s) was related to the years of experience, the score on the firm's programmer aptitude test, and gender.

Question: To test the joint significance of the two factors, test score and gender, in Model 1, given, the conclusion of the test is

Model 1:

	Coefficients	Standard Error
Intercept	9.3536	6.2008
experience	1.4888	0.1829
Test score	0.1851	0.0757
female	-2.3613	1.0607

SST=599.7855, SSE= 75.9380

a. not rejectH₀ and test score and gender are jointly insignificant.

b. rejectH0 and test score and gender are jointly significant.

c. rejectH0 and test score and gender are jointly insignificant.
