Just giving the answer without adequate work/explanation may result in zero for the question. A national bank determined that the annual interest earned by its checking-account customers is approximately normally distributed with a mean $260 and a standard deviation $100. 1. What is the probability that a randomly chosen bank's customer earns more than $340 annually on the interest-checking plan? 2. What is the probability that a randomly chosen bank's customer earns between $250 and $300 annually on the interest-checking plan? 3. Only 10% of the bank's customers earned more than dollars of annual interest on checking. Find the value of . 4. Suppose you take a random sample of 25 bank customers and calculate the sample mean annual interest. What is the distribution, mean and the standard deviation of the sampling distribution of sample mean? 5. What is the name of the theorem that tells you the sampling distribution of the sample mean? 6. What is the probability that average annual interest of 25 customers is more than 265?
A lоcаl pizzа pаrlоr has 10 wоrkers and a manager. Monthly salary of each of the 10 workers is considerably less than what the manager is getting paid. If mean and the median are calculated for these 11 people,
