PLEASE SHOW ALL WORK

A laboratory scale is known to have a standard deviation of a = 0.001 gram in repeated weighings. Scale readings in repeated weighings are Normally distributed, with mean equal to the true weight of the specimen. Three weighings of a specimen on this scale give 3.412, 3.416, and 3.414 grams. You want a 99% confidence interval for the true weight of this specimen. The margin of error for this interval will be which of the following? about the same as the margin of error for 95% confidence smaller than the margin of error for 95% confidence greater than the margin of error for 95% confidence

Explanation / Answer

Larger confidence levels yield wider (greater margin of error) confidence intervals.

Thus,

OPTION C: GREATER THAN THE MARGIN OF ERROR FOR 95% CONFIDENCE [ANSWER]
