Texas is home to more than one million undocumented immigrants and most of them are stuck in low-paying jobs.  Meanwhile, the state also suffers from a lack of skilled workers.  The Texas Workforce Commission estimates that 133,000 jobs are currently unfilled, many because employers cannot find qualified applicants.  Texas was the first state to pass a law that allows children of undocumented immigrants to pay in-state college tuition rates if they have lived in Texas for three years and plan to become permanent residents.  The law passed easily back in 2001 because most legislators believed that producing college graduates and keeping them in Texas benefits the business community.  In addition, since college graduates earn more money, they also provide the state with more revenue.  Carol Capaldo wishes to estimate the mean hourly wages of 30 Texas workers with a bachelor's degree or higher, 30 Texas workers with only a high school diploma, and 30 Texas workers who did not finish high school.The attached Excel data file contains the hourly wage of Texas workers based on the three education levels; bachelor's degree, high school diploma, no high school diploma.  In a report, use the above information to: 1. Use descriptive statistics to compare the hourly wages of the three education levels. 2. Construct and interpret 95% confidence intervals for the mean hourly wage at each education level.

Need help with the following: In your own words, explain how to obtain the “expected value of perfect information” for any payoff table, which has probabilities associated with each state of nature. Then, provide an example, drawing from any of the payoff tables in Problems 1-17 in the back of Chapter 12. If no probabilities are given for the states of nature, then assume equal likelihood. Problem: A local real estate investor in Orlando is considering three alternative investments: a motel, a restaurant, or a theater. Profits from the motel or restaurant will be affected by the availability of gasoline and the number of tourists; profits from the theater will be relatively stable under any conditions. The following payoff table shows the profit or loss that could result from each investment Gasoline Availability Investment Shortage Stable Supply Surplus Motel $-8,000 $15,000 $20,000 Restaurant $2,000 $8,000 $6,000 Theater $6,000 $6,000 $6,000 Determine the best investment, using the following decision criteria.
