The average oversea tip cost is $2708 per visitors. If we assume a normal distribution with a standard distribution of $405, what is the probability that the cost for a randomly selected tip is more than $3000? If we select a random sample of 30 oversea tips and find the mean of the sample, what is the probability that the mean is greater than $3000? Explain?
