A laboratory scale is known to have a standard deviation of σ = 0.001 gram in repeated weighings. Scale readings in repeated weighings are Normally distributed, with mean equal to the true weight of the specimen. Another specimen is weighed eight times on this scale. The average weight is 4.1602 grams. You want a 99% confidence interval for the true weight of this specimen. The margin of error for this interval will be Group of answer choices

a. smaller than the margin of error for 95% confidence.

b. greater than the margin of error for 95% confidence.

c. about the same as the margin of error for 95% confidence.
