Benign prostatic hyperplasia is a non-cancerous enlargement of the prostate gland that adversely affects the quality of life of millions of men. A study of a minimally invasive procedure for the treatment of this condition looked at pretreatment Quality of Life (QOL Base) and Quality of Life (QOL 3Mo) after 3 months on treatment. Quality of Life was rated using an ordinal scale of 0 to 6, where 0 is "Delighted" and 6 is "Terrible" Create a "Delta" column depicting the Difference between the Base and 3-month ratings Find the Mean of the Differences, Standard Deviation and Standard Error for the Delta values Is there a Significant Difference in Quality of Life 3 months after treatment? Find the tsat value and the corresponding p-value boundaries using Table C
This activity demonstrates how to create graphics to enhance the presentation of quantitative data Scenario The sales manager for a small manufacturer is interested in marketing the company's rain coat line in a new area of the country. As a first step to establishing a marketing plan she has asked you to produce some graphs showing the market share of the products sold over the past several years in the region. Analysis After some research, you acquire the approximate sales for each of the competing products presently in the region under consideration (See the data given below). The question now is to show how best to organize the data to take advantage of a graphical analysis. Pie charts give a quick overview of the market share "slices” each competitor presently enjoys. So you decide to use a pie chart to graph the most recent year's sales data for the region. This will give a good indication of just who the market leaders are and how crowded it is at the top. Next, you decide to…
Elaine is interested in determining if men are more satisfied in their jobs than women in the healthcare industry. She administers a job satisfaction questionnaire to 20 men and 20 women working in hospital administration. Her grouping variable is gender and dependent variable is job satisfaction. The job satisfaction scale consists of 8 items measured using a 5-point rating scale. A higher score on this scale would indicate high job satisfaction. The maximum score that can be obtained on the scale is 40. We can assume that job satisfaction scores are normally distributed. Use the appropriate T test with a significance level of 0.05 to test the hypothesis. Research Question Do the mean job satisfaction scores differ for men and women working in the hospital administration department? Hypothesis The mean job satisfaction scores do not differ for men and women working in the hospital administration department. Compute an independent sample t test on these data. Report…
