A test of H0: mu = 60 vs Ha: mu != 60 yields t = 2.45, p = 0.018 (df = 24).
The best conclusion at alpha = 0.05 is:
- Acheck_circle
There is convincing evidence that mu differs from 60.
- B
The mean is exactly 62.
- C
There is no evidence at all about mu.
- D
There is convincing evidence that mu = 60.
Explanation
p < 0.05 leads to rejecting H0, providing evidence that mu is different from 60.
