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 = 
Hence we have
\frac{211}{\sqrt{n} }
The minimum sample size is 1710

Answer:
but u have only provided 5 pts first give 100 pts and I will help u.
Answer:
C.
Step-by-step explanation:

3+p=8
-p -p
3=8-p
-8 -8
-5=-p
swap signs
5=p
