In the past, the average age of employees of a large corporation has been 40 years. Recently, the company has been hiring older individuals. In order to determine whether there has been an INCREASE in the average age of all the employees, a sample of 25 employees was selected. The average age in the sample was 45 years. Assume the distribution of the population is normal with a standard deviation of 5 years. Let α = .05. P value=2.8 Therefore, reject H0. There is No sufficient evidence at α = .05 to conclude that average age of all employees of the large corporation has increased. P value=0 Therefore, Do Not reject H0. There is sufficient evidence at α = .05 to conclude that average age of all employees of the large corporation has increased. P value=0 Therefore, reject H0. There is sufficient evidence at α = .05 to conclude that average age of all employees of the large corporation has increased. Hyphotheses: H0: Ha: Sample: n= Mean= s= z= P-value= One tailed test

Use Excels functions (not @RISK) to generate 1000 random numbers from a normal distribution with mean 100 and standard deviation 10. Then freeze these random numbers. a. Calculate the mean and standard deviation of these random numbers. Are they approximately what you would expect? b. What fraction of these random numbers are within k standard deviations of the mean? Answer for k = 1; for k = 2; for k = 3. Are the answers close to what they should be (about 68% for k = 1, about 95% for k = 2, and over 99% for k = 3)? c. Create a histogram of the random numbers using about 10 bins of your choice. Does this histogram have approximately the shape you would expect?

Records pertaining to the monthly number of job-related injuries at an underground coal mine were being studied by a government agency. The values for the past 100 months were as follows: Injuries Frequency of per Month Occurrence 32 40 2 15 3 4 1. 1. Apply the chi-square test to these data to test the hypothesis that the underlying distribution is Poisson. Important note: In the answer box below, just put the numerical test statistic value. Use x.xx format for the numerical value you provide as the answer. Do NOT compare the test statistic with the critical value from a table. Answer:
