Suppose that the annual employer participation in the Canada/Quebec Pension Plan (CPP/QPP) per employee is normally distributed with a standard deviation of $625, but the mean is unknown. If 73.89% of such employer contribution are greater than $2,00O, what is the mean annual employer contribution per employee? Suppose the mean annual CPP/QPP employer contribution per employee is $2,261 and the standard deviation is $625. If such employer contributions are normally distributed, 31.56% of the contributions are greater than what value?
