Scenario: You are the manager of a ER clinic. You are planning for the month of October and want to know what expected patient daily volume will be. Use Linear predication to forecast daily patient volume based on data for the month of October. Present your forecasts based on your findings. Your IT department provided you data on patient daily volume for the month of October. Prepare a report to share with the owners of the facility that will help you make informed decisions about planning for the next month. Prepare a report that addresses each of these areas. Forecasting: Monthly Patient Volume. (30 points) Purpose Importance Variables Sample Size Methodology Findings /Result in APA format Interpretations/Implications

The administrator at your local hospital states that on weekends the average wait time for emergency room visits is 10 minutes. Based on discussions you have had with friends who have complained on how long they waited to be seen in the ER over a weekend, you dispute the administrator's claim. You decide to test you hypothesis. Over the course of a few weekends you record the wait time for 40 randomly selected patients. The average wait time for these 40 patients is 11 minutes with a standard deviation of 3 minutes. Do you have enough evidence to support your hypothesis that the average ER wait time exceeds 10 minutes? Use a 5% level of significance. State the null and alternative hypotheses. (2.5 pts) Ho: u = 10 Ha: u (does not equal) 10 Manually calculate the test statistic. Make sure you write down the appropriate formula. Show your work. Do not use technology to solve this problem. (5 pts) Manually calculate the p-value for this test? Use StatKey or other technology to draw a picture of a standard normal curve and shade in the appropriate area for the p-value. (5 pts) What is the correct conclusion of the test? Use ?=0.05. (2.5 pts)

Physician Demand The demand for physicians is expected to increase in the future, as shown in the table. Source: Association of American Medical Colleges. (a) Plot the data, letting $t=0$ correspond to $2000 .$ Does fitting an exponential curve to the data seem reasonable? (b) Use the data for 2006 and 2015 to find a function of the form $f(t)=C e^{k t}$ hat goes through these two points. (c) Use your function from part (b) to predict the demand for physicians in 2020 and $2025 .$ How well do these predictions fit the data? (d) If you have a graphing calculator or computer program with an exponential regression feature, use it to find an exponential function that approximately fits the data. How does this answer compare with the answer to part (b)?
