A classic experiment in the 1960s eloquently illustrated the technical side of conservatism bias. The researchers presented subjects with two urns: one containing 3 blue balls and 7 red balls, the other containing 7 blue balls and 3 red ones. Subjects were given thisinformation and then told that someone had drawn randomly 12 timesfrom one of the urns [with replacement]. Subjects were told that thisdraw yielded 8 reds and 4 blues. They were then asked, "What is theprobability that the draw was made from the rst urn?" Formulate the problem in terms of Bayes' Rule. State all of your assumptions and all assignments explicitly.

A light bulb manufacturer guarantees that the mean life of a certain type of light bulb is at least 753 hours. A random sample of 28 light bulbs has a mean life of 726 hours. Assume the population is normally distributed and the population standard deviation is 64 hours. At alphaequals0.05, do you have enough evidence to reject the manufacturer's claim?

Three friends share a full bag of jellybeans. Mike took 1/3 of the jellybeans in the full bag, Zac took 1/2 of the jellybeans in the full bag and Kary took what was left. Mike ate 1/2 of his jellybeans, Zac ate 1/3 of his jellybeans and Kary ate all of hers. If Mike and Zac now have a total of 45 jellybeans together, how many jellybeans did Kary eat?

Isaac wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence on that side. The other three sides will be enclosed with wire fencing. If Isaac has 550 feet of fencing, you can find the dimensions that maximize the area of the enclosure. a) Let w be the width of the enclosure (perpendicular to the barn) and let l be the length of the enclosure (parallel to the barn). Write an function for the area A of the enclosure in terms of w. (HINT first write two equations with w and l and A. Solve for l in one equation and substitute for l in the other). b) What width w would maximize the area?c) What is the maximum area?

A major tire manufacturer wishes to estimate the mean tread life in miles for one of its tires. It wishes to develop a confidence interval estimate that would have a maximum sampling error of 500 miles with 90 percent confidence. A pilot sample of n=50 tires showed a sample standard deviation equal to 4,000 miles. Based on this information, what is the required sample size?
