Two questions For each of the following questions: clearly indicate the probability distribution being used to solve the problem solve by hand, and verify your answer using MATLAB. 1. Two teams, A and B, play a series of games. If team B has a probability 0.4 of winning each game, is it to their advantage to play the best three out of five games or the best four out of seven, and why? Assume the outcomes of successive games are...

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...

The random sample showed an average of 28,350 kilometers and a standard deviation of 5,237 kilometers. Assuming the underlying population is normally distributed, test the hypothesis that automobiles are driven on average more than 28,000 kilometers per year at the 10% level.
