The following attached file presents the annual returns for two mutual funds offered by the investment giant Fidelity. The Fidelity Select Automotive Fund invests primarily in companies engaged in the manufacturing, marketing, or sales of automobiles, trucks, specialty vehicles, parts, tires and related services. The Fidelity Gold Fund invests primarily in companies engaged in exploration, mining, processing, or dealing in gold and, to a lesser degree, in other precious metals and minerals.

In a report, use the above information and attached file to

1. Calculate descriptive statistics to compare the returns of the mutual funds using the Data Analysis Descriptive Box.
2. Compare and interpret the mean, median and skewness of Fidelity Select Automotive Fund and Fidelity Select Gold Funds.

3. Compare and interpret the range and the standard deviation of Fidelity Select Automotive Fund and Fidelity Gold Funds.
4. Discuss the range of each funds returns? Is the range the best descriptive measure? Why or Why not?
5. Assess reward by constructing and interpreting 95% confidence intervals for the population mean return. What assumption did you make for interval estimates?

Example p. 314/ Note Use standard deviation as a measure of risk!

(5.15) Manatees are large, gentle, slow-moving creatures found along the coast of Florida. Many manatees are injured or killed by boats. below contains data on the number of boats registered in Florida (in thousands) and the number of manatees killed by boats for the years between 1977 and 2013. (data are distorted):

(a) Find the correlation rr (±±0.001)

rr =

(b) Find the equation of the least-squares line (±±0.001) for predicting manatees killed from thousands of boats registered.

yˆy^ = +xx

(c) What would you predict (±±0.1) number of manatees killed by boats to be if there are 900,000 boats registered?

(d) Predict (±±0.1) manatee deaths if there were no boats registered in Florida.

You have the following   data on quantity demand of commodity X and its price and other factors during 1991-2005:-

Based on the above data:-

1. Draw the relationship between Q & P?
2. Using the OLS, estimate the demand function in linear form.
3. Comments on the results by taking into account any prior expectations you have about demand functions.

      4) Compute the predictable value of the dependent variable & the residuals?

     5) How much the change in Px, Py and Expenditures ( M) explains the variations in Q?

       6) Interpret the empirical results of the estimated equation?

        7) Calculate demand elasticities at the mean.

        8) Construct a confidence internal at 95% of estimated own price elasticity at the

            mean   and in the year of 2005?

         10) Construct a confidence interval of the quantity demanded in the years 2005 and in

         the year 2008 when Px=7, Py=3.5 ,Expenditures =1900

Above is a CSV file from the file do the following:

(a) Subset the data to include only those from 1947 to 1964.

(b) Fit a linear regression model, M1, to model population as a function of the year using this data from 1947 to 1964.
(c) Predict the population for the missing years 1955 and 1960.
(d) Plot the population versus Year including the predicted values for 1955 and 1960 in the range 1947 to 1964. The predicted values must be annotated (marke
