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...

please help me answer this, thank you!
In an advertising campaign, a snack company claimed that every 18-ounce bag of its cookies contained at least 1000 chocolate chips. Two statisticians attempted to verify the claim. The accompanying data represent the number of chips in an 18 ounce bag of the company's cookies based on their study.
