4. A man claims to be able to distinguish between two kinds of winewith 90% accuracy and presents his claim to an agency interested inpromoting the consumption of one of two kinds of wine. The followingexperiment is conducted to check his claim. The man is to taste thetwo types of wine and distinguish between them. This is to be donenine times with a 3-minute break after each taste. Assume that eachtasting is independent. It is agreed that if the man is correct at leastsix out of the nine times, he will be hired.(a) Assume that the man is guessing. What is the likelihood of theman being hired?(b) Assume now that the man's claim is true (i.e. that his probabilityof success in each tasting is 0.9). What is the chance of the manbeing hired?

A test is being designed to compare the wearing quality of two brands of tires, say brand A and brand B. Six automobiles will be selected and equipped with the new tires from both brands and driven under normal conditions for 1 month. A measurement will be taken to determine how much wear took place on a scale from 0 to 200. Below is a table of the paired data collected from the 6 cars in the test.

Use the following scenario to answer the next 6 questions: M&Ms are your favorite vending machine snack and you purchase them often. Lately, it seems like the bags have been having a disproportionate distribution of the colors. The company claims that 24% of the candies per bag should be blue.
