evablogger [386]

Answer:

Step-by-step explanation:

Given that confidence level is 95% and sample mean is within 10 minutes of the population mean. i.e. margin of error = 10

Std deviation of population= 211 minutes

Margin of error = Z critical * std error

Std error = sigma/sq rt n = $\frac{211}{\sqrt{n} }$

Hence we have

\frac{211}{\sqrt{n} } $\frac{211}{\sqrt{n} }*1.9641.356\\n>1710$

The minimum sample size is 1710
