When "S" is used to estimate "$\sigma$," the margin of error is computed by using
A)normal distribution
B)t distribution
C)the mean of the sample
D)the mean of the population

Question

Quizplus · Accepted Answer

When estimating a population standard deviation using a sample standard deviation, the margin of error should be computed using the t distribution, as the population standard deviation is not known. The t distribution takes into account the additional uncertainty caused by using a sample statistic instead of a population parameter.
