I will attach page that needs to be filled out. I will also attached the user Manuel for Stat disk.
Tech App 1 Week 4 Project - STAT 3001 Student Name: Jackie Burns Date:10-22-21 Instructions: To complete this project, you will need the following materials: · Statdisk User Manual (link found on Project resources page) · Access to the Internet to download the Statdisk program. · You don’t have to explain your steps unless the problem specifically says to. Part I. Analyze Data Instructions Answers 1. Open the file Body Temperatures using menu option Datasets and then Elementary Stats, 13th Edition. This file contains information on the body temperature of men and women at different times of the day. How many observations are there in this file? 2. What results do you expect to find in this data relative to the body temperature? Part II. Descriptive Statistics 3-6 Generate descriptive statistics for all three groups of people and complete the following table. Round all results to 2 decimal places. Variable Sample Mean Sample Standard Deviation Sample Size 3. Day 1 8AM 4. Day 2 8AM 5. Day 2 12AM 7. Did you get the results you expected here? Explain why. 8. In which of the three groups did we experience the MOST variation (highest deviation from the mean)? Part III. Confidence Intervals 9. Generate a 95% interval for the hanging mean of Day 1 8AM. Paste your results here. 10. Generate a 95% interval for the mean of Day 2 8AM. Paste your results here. 11.Generate a 95% interval for the mean of Day 2 12AM. Paste your results here 12. Create a graph below by illustrating all three confidence intervals on one graph using the tools in your word processor (example below). Statdisk cannot do this for you. Create your graph and turn the font red. For this process, I just used dashes and wrote a scale below the axes. Here is an example, but it is not based on the data you are analyzing: Case 1 14---------------------42 Case 2 35-------------------------70 ________________________________________ 0 20 40 60 Your Solution: 13. Based on the confidence intervals shown above, does there appear to be some evidence to indicate that time of day relates to temperature? Part IV. Hypothesis Testing 14. Let’s say that you are trying to show that the mean body temperature on day 1 at 8AM is more than 98.6 degrees. Use an alpha of 0.01. Step 1. Determine parameter of interest and compose null and alternative hypotheses. Step 2. Determine the sample mean, sample standard deviation, and sample size. [Hint: You did this in an above step in this assignment.] Step 3. Determine the likelihood that the population mean is greater than 98.6 degrees by completing a Hypothesis Test: One Mean in Statdisk. Use significance of 0.01. Paste results here. Remember that the pulldown menu in Statdisk must match the alternative hypothesis statement. Step 4. State your conclusion. The conclusion statement has a prescribed format: it should include a comparison of the p-value and alpha, whether you reject or support the null hypothesis, and a paraphrase of the hypothesis supported by the data. 15. Now test the claim that the mean body temperature on day 2 at 8 AM is less than 98.2 degrees. Use a significance level of 0.05. Step 1. Determine parameter of interest and compose null and alternative hypotheses. Step 2. Determine the sample mean, sample standard deviation, and sample size. [Hint: You did this in an above step in this assignment.] Step 3. Determine the likelihood that the population mean is actually less than 98.2 degrees by completing a Hypothesis Test: One Mean in Statdisk. Use significance of 0.05. Paste results here. Remember that the pulldown menu in Statdisk must match the alternative hypothesis statement. Step 4. State your conclusion. The conclusion statement has a prescribed format: it should include a comparison of the p-value and alpha, whether you reject or support the null hypothesis, and a paraphrase of the hypothesis supported by the data. 16. Answer the following questions based on the above hypothesis test. a. What is the p-value in this example and what does it represent? b. Given that your data, hypotheses, and p-value do not change, what would need to be changed in order for us to FAIL TO REJECT the null hypothesis? Submit the final draft of your Word file by going to Week 4, Project, and follow the directions.

Be certain that you are using Version 13.0.0. Click on the OK button to close the Statdisk information screen. Figure 1 You can perform all Statdisk functions from the Sample Editor Screen. The top of the screen has the following menus: File, Edit, Analysis, Data, Datasets, Window, and Help as shown in Figure 2. Figure 2 Along with performing statistical calculations, Statdisk is also compatible with many popular software application packages. You can import, copy, paste, save, print and transform data sets. You can also copy, paste, save, or print any of the Statdisk numerical or graphical outputs and export them into other programs such as Microsoft Word. Those options are available as clickable buttons at the top of the Sample Editor screen as shown in Figure 3. Figure 3 Statdisk User Manual 4 Opening a File Statdisk has numerous datasets stored in the program and can be accessed by clicking on Datasets at the top of the Sample Editor window. After opening Datasets go to Elementary Statistics 13th Edition. The names of the datasets will appear to the right. Click on Body Data and the data values will appear in the Sample Editor as shown in figure 4. Figure 4 You can preview the datasets quickly by opening a data set, review the data, and then select Clear to move in to the next file. You can also access datasets that Statdisk has available online by going to Help and then Triola Statistics Series. Using Data Tools After you have opened a dataset or have typed in data to the Sample Editor, you can edit column titles, sort data, delete columns, add columns or rows, or explore the data set by opening the Data Tools menu. The Data Tools button is located at the top of the Sample Editor page. To Edit column titles open up Data Tools and then Edit column titles. Type in the names of the column titles into the box shown in Figure 5. Statdisk User Manual 5 Figure 5 Click on the Save Changes button to enter the new column titles. Copy and Paste The Copy button is at the top of the Sample Editor Screen. To copy columns from a data set simply click on the Copy button and a screen will appear asking you which column of data you want to copy (see figure 6). You can copy all of the columns or select columns. To Paste the column of data values into another column. Click on the column title (or number) then open the Edit menu and select Paste. Figure 6 Statdisk User Manual 6 Sort Data To sort data, select Data Tools and then select Sort Data. Use the drop-down arrow to select Sort One column, then select the column title and order from A to Z (see figure 7). Then click on Sort. The data values in that column will be sorted from lowest value to highest value. Figure 7 The Data Menu The two main menus in Statdisk are Analysis and Data. The Data menu is used to sort data, add data, transform data, generate descriptive statistics including charts and graphs, assess normality and generate sets of data values that emulate one of the standard types of statistical distributions. The Analysis menu is use to find area under the curve for many of the standard statistical distributions, determine sample size, create confidence intervals, perform hypothesis tests for parametric and non- parametric models. Using the Data Menu To transform a dataset you first need to type data into the sample editor or select an existing dataset. Open the Body Data file that was referenced in Opening a File earlier in the manual. Select Data and then Sample Transformations to open the Sample
