Answer :
Final answer:
The sample mean is 95.
Explanation:
To find the sample mean from a given confidence interval, we can take the average of the lower and upper bounds of the interval. In this case, the confidence interval is 90 to 100. To find the sample mean, we add the lower bound (90) and the upper bound (100) and divide the sum by 2:
(90 + 100) / 2 = 190 / 2 = 95
Therefore, the sample mean is 95.
