Question

Solve For: For a normal distribution, assume the 'population' standard deviation is 14.7. What is the maximal margin of error associated with a 95% confidence interval for the true population mean if n = 61. (Round to two decimal places)

Answer 1

margin of error = critical z * standard deviation/square root(sample size)

critical z for 95% Ci is 1.96

standard deviation and sample size are given
