Answer:
61.57
Step-by-step explanation:
Sample size (n) = 32
Sample mean hardness (X) = 64.3
Sample standard deviation (s) = 6.0
Z-score for a 99% confidence interval (Z) = 2.576
The lower confidence bound (L) for a confidence interval is determined by the following expression
Applying the given data:
For the given material, the lower confidence bound for true average Brinell hardness is 61.57.
