1. A seafood restaurant often receives complaints from it’s patrons that the lobster is too small. The menu lists the weight of a lobster as 462g. The next time the restaurant receives a batch of 60 lobsters it weighs them and finds the average is 449g with a standard deviation of 31g. Do you think the restaurant sells lobsters that are smaller than advertised? Perform a hypothesis test at α = 0.01

2. The lifespan of a fruit fly is normally distributed with an average of 40 days and a standard deviation of 7.4 days.

If we take a sample of 80 fruit flies, what is the probability the sample mean is within 1 day of the population mean?

1. In his analysis of the Dell fraud for Forbes, Edward Hess comments: "Too often, the market's maniacal focus on creating ever-increasing quarterly earnings drive bad corporate behavior, as it apparently did at Dell. That behavior produces non-authentic earnings that obscure what is really happening in business. Short-termism can result in a range of corporate and financial games that may enrich management at the expense of market integrity and efficient investor capital allocation." Comment on Hess's statement from two perspectives:...

Consider a bank account starting with $1 (if $1 seems too small to you, you are welcome to multiple this and all other results by any desired amount, say, $1,000 or $100,000). If the bank gives you 100% interest rate (yes, I know, it’s not realistic, but just play along!), then after one year you have $2 in your account. 1) What will happen if instead the bank gives you 50% interest every half a year? How much money will...
