Solving normal distribution problems

Web1 Answer. The problem asks us to suppose that the true mean is 50 % ("Assuming that the machine is working properly …. "). If that is the case, then the number X of pink in a sample of 50 has binomial distribution, mean 25, variance ( 50) ( 0.5) ( 0.5). So for our problem, the mean and standard deviation can be considered as known.
