Question

The margin of error for a confidence interval for a population is equivalent to the standard deviation times the z-score value, or t-score value depending on the size of the population, for the probability of interest times the standard deviation of the population. True or False

Answer 1

Result:

The margin of error for a confidence interval for a population is equivalent to the standard deviation times the z-score value, or t-score value depending on the size of the population, for the probability of interest times the standard deviation of the population. True or False

Correct option: False

margin of error = z*σ/sqrt(n) when population standard deviation is known

or

margin of error =t*s/sqrt(n) when population standard deviation is not known, s is sample deviation
