1. Select two variables from the Data Bank that you think might have a linear relationship. Explain why you picked these two variables. Discuss which variable is the independent variable and which is the dependent variable. You may use your text, outside resources, or your own experiences in your explanation. 2. Select a simple random sample of at least 30 records from the Data Bank, Do this by using a random number table, or the random number generator on your calculator. Explain your method. Record the raw data for your sample in a table to show the independent variable and the dependent variable. 3. Find the mean, median, mode, variance, and standard deviation for each variable. 4. Create a scatterplot. You may do this by hand or by using Excel, Minitab, or your calculator. 5. Calculate r. You may do this by hand, or by using technology. 6. Conduct the appropriate hypothesis testing to see if there is a significant relationship. You may use either the traditional method or the p-value method. Be sure to state your hypothesis (both the null and alternate) Find the test value Find the p-value method (or the critical value) Make the decision to reject
