Question
Using = .05, is a significant relationship present?
SelectThe overall model is significantThe overall model is not significantItem 11
Did the estimated regression equation provide a good fit to the data?
SelectYes, it provided a good fitNo, it did not provide a good fitItem 12
Use the t test and = .05 to test H0: 1 = 0 and 2 = 0.
Compute the t test statistic for 1 (to 2 decimals).
What is your conclusion?
SelectSignificant relationship between length of service and job satisfactionNo significant relationship between length of service and job satisfactionItem 14
Compute the t test statistic for 2 (to 2 decimals).
What is your conclusion?
SelectSignificant relationship between wage rate and job satisfactionNo significant relationship between wage rate and job satisfactionItem 16

Explanation / Answer
Rsquared = SSR/ SST = 648.83/720 = 90.12%
Adjusted R squared = 1 - [(1 - Rsquared)(n-1)]/(n-k-1)
= 1 - [(1-0.2857)×8/5]
= 1 - 0.1582 = 84.18%
F = 324.42/14.234 = 22.79
F(2,5) = 5.79
Reject Ho and conclude that the overall model is significant
Yes it provide a good fit
T test statistics for 1 = 1.76
t0.025 = 2.571
tcal < t0.025
Do not reject Ho and conclude that there no significant difference between length of service and job satisfaction.
T test statistics for 2 = -5.59
|tcal | > t0.025
Reject Ho and conclude that there is a significant relationship between wage rate and job satisfaction.
