Given the question in the picture below: The mean and standard deviation of the resistors are given by u = 220 N and o = 11 .a. Given a random sample of 70 resistors, what is the probability that its mean is between 218 nand 223 N?b. What is the probability that two samples 50 and 60 resistors, taken by random, will differ intheir mean by more than 5 N.

HERE GIVEN, mean = 220 standard deviation = 11 here use central limit theorem

Answered: a. Given a random sample of 70…
