Consider the following realized annual returns:

1. 2005	-11.3%	52.7%
   2006	-20.8%	-22.0%
   2007	33.1%	6.9%
   2008	13.0%	9.2%
   2009	7.3%	-0.9%

2. Consider the following realized annual returns:
   
   
   
   
   
   
   
   
   

3. Q1 : Suppose that you want to use the 10 year historical average return on the Market to forecast the expected future return on the Market. Calculate the 95% confidence interval for your estimate of the expect return. Q2 : Using the data provided in the table, calculate the average annual return, the variance of the annual returns, and the standard deviation of the average returns for Stock B from 2000 to 2009.

1. the annual precipitation measurements (Pi in cm) for M city, over a 20year period are shown in the following table. Determine the mean, standard deviation, and skew coefficient for this series.

2. Determine the mean, standard deviation, and skew coefficient for the log values of annual rainfall for M City, given in Problem 1. Also determine the mean precipitation (in cm) of the log-transformed data.

Please clarify each step of the solution.

The following table provides the project annual budget, total number of projects, and total number of people working on the projects for City of Killingcovid annually:

For A to F, use the data between Yr 2006 and Yr 2015 to calculate the following:

A. The mean of the Number of People Working on the Project.
B. The median of the Budget.
C. The range of Budget.
D. The variance (3 significant figures) of Number of Projects.
E. The standard deviation (nearest integer) of Number of People Working on the Project.
F. The 20% trimmed mean of Number of Projects.

G. Draw a dot plot comparing the Number of People Working on the Project from Yr 1997 to Yr 2006 and those from Yr 2009 to Yr 2018.

H. Using the data for Annual Budget from Yr 2001 to Yr 2017, draw a double stem leaf plot, then calculate the relative frequency.

Alternative-Fueled Vehicles The table shows the numbers (in thousands) of alternative-fueled

vehicles A in use in the United States from 1995 to 2011. (Source: U.S. Energy Information Administration)

(a) Use a graphing utility to plot the data. Let t represent the year, with t = 5 corresponding to 1995. (b) A model for the data is

4615.36t − 8726.7

1 + 15.01t − 0.542t2, 5 ≤ t ≤ 21

where t = 5 corresponds to 1995. Use the model to estimate the numbers of alternative-fueled vehicles in 1996, 2006, and 2011. How do your answers compare to the original data?

(f ) Use the model to predict the numbers of alternative-fueled vehicles in 2016 and 2017

* Need help to understand F . Should I be using a particular formula

The issues surrounding the levels and structure of executive compensation have gained added prominence in the wake of the financial crisis that erupted in the fall of 2008. Based on the 2006 compensation data obtained from the Securities and Exchange Commission (SEC) website, it was determined that the mean and the standard error of compensation for the 582 highest paid CEOs in publicly traded U.S. companies are $12.01 million and $11.38 million, respectively. An analyst randomly chooses 31 CEO compensations for 2006 a. Is it necessary to apply the finite population correction factor? b. Is the sampling distribution of the sample mean approximately normally distributed? c. Calculate the expected value and the standard error of the sample mean. d. What is the probability that the sample mean is more than $17 million?
