Problem 7 Question Help * David Polston prints up T-shirts to be sold at local concerts. The T-shirts sell for $24.20 each but cost David only $8.90 each. However, because the T-shirts have concert-specific information on them, David can sell a leftover shirt for only $1.00. Suppose the demand for shirts can be approximated with a normal distribution and the mean demand is 380 shirts, with a standard deviation of 65. Click the icon to view the normal probability table...
