I'm stuck on this two question problem. Please help out and show me to work these types of problems.
A sample of 500 evening students revealed that their annual incomes from employment in industry during the day were normally distributed with a mean income of $30,000 and a standard deviation of $3,000. Show your work!
How many students earned more than $30,000? _______________
How many students earned between $27,000 and $33,000? _______________
Thanks
