A 95% CI for the proportion of left-handed students is (0.08, 0.14).
Which interpretation is INCORRECT?
- A
If we repeated the procedure many times, ~95% of intervals would contain p.
- Bcheck_circle
The probability that p is between 0.08 and 0.14 is 0.95.
- C
We are 95% confident p is between 0.08 and 0.14.
- D
The interval is plausible for p at the 95% level.
Explanation
The parameter p is fixed; we cannot assign probability to a single fixed-but-unknown value being in a fixed interval.
