section.
Question 1 answers
1a: forecast $4812.7143
1b: reliability The value of significance F (0.037) is less than the default significance
level of 0.05. Hence, we are 95% confident that forecast made using the
regression model is accurate.
Question 2 answers
2a: formula Y =1.3232 β0 +0.0773 β1 −0.1700 β2 −1.5224 β3 + 98.3291
Where Y is Job satisfaction, β0 is Relationship with supervisor, β1 is
opportunities for advancement, β2 is overall quality of work
environment, and β3 is total hours worked per week. The intercept is
98.3291.
2b: reliability The coefficient of determination is 0.823 (82.3% variation) and the
value of significance f is 3.74 x 10−5 and is less than 0.05 significance
level. Therefore, there is a 95% reliability that 82.3% of the estimate
will be based on the multiple regression formula.
2c: variables  Opportunities for Advancement
 Overall quality of work environment
They are not good predictors because they are not statistically

significant.
2d: expected
score
Job satisfaction score is equal 49.4821 which can be rounded off to a
job satisfaction of 50.
Question 3 answers
Yes, bond rate can be predicted by the prime interest. This because the coefficient of
determination or the R-square value shows that 91.94% of the variation in bond rate can be
explained by prime interest rate. Moreover, the regression equation shows that there is a positive
linear relationship between bond rate and prime interest rate. The square root of R-square value
which is 0.9588 indicates that 95.88% of the relationship between bond rate and prime interest
can be explained by the equation developed.
The scatter plot of bond rate against prime interest is illustrated in the figure below.
