26. Alternative
27. Complementary 
28. Normal
29. Z – test
30. Rejection region
31. Critical 
32. rejects Null hypothesis when it is true.
33. that is tested
34. significance level, hypothesis
35. rejected
Part D
Solution 36
a) From the given output, it is given that
Intercept = – 8.859 and,
Slope of Fuel Consumed (x) = 0.132
Since, the general form of equation is 
Therefore, the estimated regression equation is
b) The number of observation is 7
No of observation = 1 + df = 1 + 6 = 7
c) F statistics 
Now, 
Therefore,
Hence, the F – statistics is 16.577
d) Since, the regression equation for Flying time is
So, for 270 Gallons of Gas, the Flying time is
Solution 37
a) The percent of the variation is explained by the R square.
So, the percent variation = 99.4%
b) The standard error of regression, s = 1.507
c) The critical value of F = 6.256 at 5% level of significance
d) The sample size is used in the print out = 10
e) Variance of slope coefficient of income,
f) Null hypothesis, 
Alternate hypothesis, At-least one of the coefficient is different than zero
Since,
We reject null hypothesis i.e. at-least one of the coefficient is different than zero.
