The average weekly starting salary of computer programmers in a city is $750 (that is μ) with a standard deviation of $40 (that is σ). The population of computer programmers in the city is 3000. Assume that we select a random sample of 64 computer programmers. 1. What is the shape of the distribution? 2. What is the probability that the sample mean will be within +/- $10 of the population mean?
