The statistical software output for this problem is:
One sample T summary hypothesis test:
? : Mean of population
H0 : ? = 4900
HA : ? > 4900
Hypothesis test results:
Mean | Sample Mean | Std. Err. | DF | T-Stat | P-value |
---|---|---|---|---|---|
? | 5157 | 114.10887 | 29 | 2.2522352 | 0.016 |
Hence,
a) Option E is correct.
b) Critical value = 1.311
Rejection region: Option A; t > 1.311
c) Test statistic = 2.25
d) Option D is correct.
e) Option C is correct.
