Homework Answers
a)
= P(-0.56 <= z <= 0.56) = P(z <= 0.56) - P(z <=
-0.56)
= 0.7123 - 0.2877
= 0.4246
b)
= P(-0.25 <= z <= 0) = P(z <= 0) - P(z <=
-0.25)
= 0.5 - 0.4013
= 0.0987
c)
= P(-2.25 <= z <= -0.93) = P(z <= -0.93) - P(z <=
-2.25)
= 0.1762 - 0.0122
= 0.164

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...
