Speeding on the I-5. Suppose the distribution of passenger vehicle speeds traveling on the Interstate 5 Freeway (I-5) in California is nearly normal with a mean of 73 miles/hour and a standard deviation of 4.65 miles/hour. Round all answers to four decimal places. What proportion of passenger vehicles travel slower than 72 miles/hour? What proportion of passenger vehicles travel between 66 and 73 miles/hour? How fast do the fastest 6% of passenger vehicles travel? miles/hour Suppose the speed limit on this stretch of the I-5 is 70 miles/hour. Approximately what proportion of the passenger vehicles travel above the speed limit on this stretch of the I-5?

A major hurricane has wind speeds of 111 miles per hour or greater. During the 20th century, the mean number of major hurricanes to strike the U.S. mainland per year was about 0.7. Find the probability that in a given year (a) exactly one major hurricane will strike the U.S. mainland, (b) at most one major hurricane will strike the U.S. mainland and (c) more than one major hurricane will strike the U.S. mainland (Source: National Hurricane Center)

The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 4639 4639 miles, with a standard deviation of 437 437 miles. If he is correct, what is the probability that the mean of a sample of 32 32 cars would differ from the population mean by less than 181 181 miles? Round your answer to four decimal places.

  1. Construct the variance-covariance matrix for the returns of the three risky assets.

  1. Compute the weights of the market portfolio. That is, show that the weight of stock 1 in the market portfolio is 1/6, the weight of stock 2 is 3/6 and the weight of stock 3 is 2/6.
  1. If CAPM assumptions hold, compute the investor’s optimal risky portfolio.

The following data is based on information taken from Winter Wind Studies in Rocky Mountain National Park by D. E. Glidden (Rocky Mountain Nature Association). At five weather stations on Trail Ridge Road in Rocky Mountain National Park, the peak wind gusts (in miles per hour) for January and April are recorded below:

Weather station 1 2 3 4 5
January 139 122 126 64 78
April 104 112 100 88 61

Does this information indicate that peak wind gusts are higher in January than in April? Use a .03 significance level. Please use the four step process and round your answers to the nearest fourth decimal place.
