Answer:
A. We are 92% confident that the population mean height of college football players is between 63.2 and 65.9 inches.
Step-by-step explanation:
Confidence interval:
x% confidence
Of a sample
Between a and b.
Interpretation: We are x% sure(or there is a x% probability/chance) that the population mean is between a and b.
In this question:
92% confidence interval for the average height of football players is (63.2, 65.9).
Interpretation: We are 92% sure that the true average height of all college football players, that is, the population mean, is in this interval.
The correct answer is:
A. We are 92% confident that the population mean height of college football players is between 63.2 and 65.9 inches.
