Did you know that diesel engines don’t have spark plugs? The cycle that diesel engines undergo involves adiabatically compressing the air in the cylinder, then injecting some fuel. When the fuel is injected it ignites if the temperature of the air in the cylinder is above the fuel’s flashpoint. Most diesel engines have a compression ratio (the ratio of the maximum to minimum volume) between 14:1 and 25:1.

a) For the given range of compression ratios, what is the range of maximum temperature (in oC) of the air in the cylinder, assuming the air is taken into the cylinder at 20oC?

b) Most gasoline engines today have compression ratios of 8:1. Explain why a diesel engine requires a better more efficient cooling system than a gasoline engine.

You have a contract with an auto parts supplier to provide spark plugs, and you guarantee no more than 2% will be faulty. You believe your manufacturing process works and the error rate is actually 1% or even less. Your customer just returned a shipment, saying that they selected 20 at random and found 2 faulty, an error rate of 10%. Was the customer justified in returning the shipment (and not paying)? You ask your chief statistician the probability that...

You have prepared 10 types of treats for your 5 cats. You don’t know which treat each of your cats will go for, so you have bought for each type enough treats for all your cats. Assume that each cat is equally likely to choose any type of treats, and let X be the number of pairs of cats that will choose the same type of treats. Compute E(X) and Var(X). (Hint: consider events Ai,j that the ith and jth...

Suppose that the market for rutabagas (in case you don’t know, it is a root vegetable that’s also known as Swedish Turnip) is competitive. The demand for rutabagas is Q = 2, 000 − 100P and the supply of rutabagas is Q = −100 + 200P. (a) (10 points) Suppose that Governor Sloop imposes a $2 per unit tax to be paid by consumers. Who bears the statutory incidence of the $2 per unit tax? Who bears the economic incidence...

Did you know that there are over 500 types of bananas in the world? Did you also know that bananas are an excellent source of potassium, fiber, and vitamin B-6 as well as serve as a powerful antioxidant? However, most people might not be aware of the prolific amount of banana consuming possibilities that are available to them. Wouldn't it be amazing if we have a program that would randomly recommend a type of banana for someone to eat every...

One of the most common complaints novice public speakers have is that they simply don’t know how to start a speech. Many times speakers get ideas for how to begin their speeches as they go through the process of researching and organizing ideas. In this chapter, we will explore why introductions are important and various ways speakers can create memorable introductions. There may not be any one “best” way to start a speech, but we can provide some helpful guidelines...

Note that the book states to use a value of 25% if you don’t know what a good value is for the population estimate. Would we want to use this value in planning election polling? Why or why not? What would be the sample sizes needed to get a 95% confidence interval of plus or minus 3% given that the initial estimate of the population proportion is either 1%, 25%, 50%, 75% or 99% (calculate the five intervals). What do...
