Statistics class homework using Minitab software.

MINITAB Assignment #2 Hypothesis Testing and Confidence Intervals Using Minitab do the following problems: Chapter 9 - 14, 40, 90, 92, 94, 98 Chapter 10 - 101, 105, 106, 109 The Write-Up The write-up for this analysis should be organized in a way that presents the results in the order in which you are prompted to do so according to the Minitab operations specified below, and your answers to the questions posed following these operations and procedures. Finally, your write-up should address the three “additional study considerations” that are presented after the completion of all the software procedures. Do not submit software; hard copy printouts of the results should be submitted. Software Procedures 1. Open Minitab. 2. In the Data (i.e., worksheet) window create your columns of data for the problems. 3. Confidence Intervals Choose Stat  Basic Statistics  Choose the test you want to perform. Click in Samples; select “the data that you want to use” If you are doing more than one sample test, Check Assume equal variances if appropriate. Click Options. For Confidence level, enter the level you want to use. For Test difference - enter the delta from your hypothesis. For Alternative, select the appropriate test. Click OK twice. Print the session window results. What are your conclusions? 4. Construct a Box and Whisker plot to examine the data. Choose Graph  Boxplot  Multiple Y’s Simple. Click OK. In Graph Variables, select variables you want to plot. Click OK. Print the plots. 5. Hypothesis tests: Choose Stat  Basic Statistics  Choose the test you want to perform. Click in Samples; select “the data that you want to use” Click on “Perform Hypothesis tests” If you are doing more than one sample test, Check Assume equal variances if appropriate. Click Options. For Confidence level, enter the level you want to use. For Test difference - enter the delta from your hypothesis. For Alternative, select the appropriate test. Click OK twice. Print the session window results. What are your conclusions? Write up – 1. You need to show the minitab results for each problem and then you need to state the confidence interval and/or draw your conclusions. The assignment should be typed and no handwriting acceptable.
