A decision maker is working on a problem that requires her to study the uncertainty surrounding the payoff of an investment. There are three possible levels of payoff -$1,000, $5,000, and $10,000. As a rough approximation, the decision maker believes that each possible payoff is equally likely. But she is not fully comfortable with the assessment that each probability is exactly 1/3, and so would like to conduct a sensitivity analysis. In fact, she believes that each probability could range from 0 to ½.
1. Show how a Monte Carlo simulation could facilitate a sensitivity analysis of the probabilities of the payoff
2. Suppose the decision maker is willing to say that each of the three probabilities could be chosen from a uniform distribution between 0 and 1. Could you incorporate this information into your simulation? If so, how? If not, explain why not, or what additional information you would need
Find the t c for a 90% confidence level with a sample size of 18.
You have to determine that your cutoff value at level a = 0.05 is 1.645 when testing whether the mean of a population is significantly different from 1.5. If you calculate a test statistic of 1.8 what is the proper conclusion?
(A) At the 0.05 level of significance, use the six step critical value approach to hypothesis testing to try and prove that the 2004 proportion has increased. (B) Use the 5 step p-value approach. Interpret the meaning of the p value.
Find a point estimate of the population mean. Find the 95% confidence interval of the population mean. Assume the variable is normally distributed.

What is the probability that a soldier is a female?
What are the theoretical parameters for the sampling distribution based on these 40 trains? Assume you are dealing with an infinite population of trains.
Craft one page brief of the statistical results (include any additional pages needed for any APA tables or graphs and the SPSS syntax and output) in which you do the following:
Suppose it costs $25 per student for the administrators to provide the course materials.
Draw a scatter diagram. Based on the scatter diagram, does there appear to be any relationship between the number assemblers and production? Explain.
Assume then money spent is uniformly distributed between these amounts. Determine the mean amount spent on insurance?
At the 5 percent level of significance, can we conclude that the mean weight is greater than 16 ounces? Determine the p- value.
