Question

Per Capita Income of Delaware Residents In a recent year, Delaware had the highest per capita annual income with $51,803. If $\sigma$ = $4850$, answer the following questions. Assume that the sample is taken from a large population and the correction factor can be ignored. Round intermediate z-value calculations to two decimal places and the final answers to at least four decimal places. Part 1 of 2 What is the probability that a random sample of 37 state residents had a mean income greater than $50,000? $P(\bar{X} > 50,000) = 0.9881$ Part: 1 / 2 Part 2 of 2 What is the probability that a random sample of 37 state residents had a mean income less than $48,900? $P(\bar{X} < 48,900) = $
