10. A research study examined the extent to which education level (measured in total years of formal education) predicted career satisfaction among a group of commer- cial airline pilots. The results of data analysis are as follows: n = 204, r = .175, RMSE = .618, t(202) = -0.708, p = .48, and y = -0.027x+2.77. Which of the following state- ments is true?

a. Education level provides nearly 20% of the information needed to perfectly pre- dict a commercial airline pilots' career satisfaction score.

b. Education level is a major predictor of commercial airline pilots' career satisfaction.

c. The prediction equation suggests that pilots with more formal education are also more satisfied in their career.

d. The regression constant is interpretable in the context of the given research setting.
