A consumer buying cooperative tested the effective heating area of 20 different electric space heaters with different wattages. Here are the results.

1. Compute the correlation between the wattage and heating area. Is there a direct or an indirect relationship? (Round your answer to 4 decimal places.) 2. Conduct a test of hypothesis to determine if it is reasonable that the coefficient is greater than zero. Use the 0.100 significance level. (Round intermediate calculations and final answer to 3 decimal places.) H₀: ρ ≤ 0; H₁: ρ > 0 Reject H₀ if t > 1.330 3. Develop the regression equation for effective heating based on wattage. (Negative value should be indicated by a minus sign. Round your answers to 3 decimal places.) 4.  Which heater looks like the “best buy” based on the size of the residual? (Round residual value to 3 decimal places.)

You are going to apply a very popular investment strategy with options called a straddle. Basically, you buy a call option and a put option for the same stock and the same maturity that are as close as possible to being at the money (stock and strike price very close to each other). First, use the information given in the spreadsheet to create the payoffs in dollars. The payoff diagram will fill in as you put in payoffs. Second, go out and choose a stock of your choice that has options traded on it and replicate a straddle strategy with real data. Yahoo Finance has easily accessible option data for stocks and can be viewed in straddle view. What conclusions can you draw from this type of strategy in terms of upside and downside as well as when do you gain and when do you lose?

Can you provide the completed table as well as the second part?

a. 1,540

b. 910

c. 1,400

d. 1,210
