Problem 1h At a 5% level of significance, use StatCrunch to conduct the appropriate test of hypothesis for the true population proportion of Variable 1's customers that have the attribute represented by the "2" code, based on the 20 data values you created for Variable 1 in your survey in Problem 1. In this problem you are to test whether the population proportion is less than 50%. In your Word solution file, under a subheading entitled Problem 1h, display all the steps using the "4 step P-value Approach". Copy and paste the Hypothesis Test Results window (that displays the correct test statistic and P-value) from StatCrunch to your Word solutions file under Step 2 of the test. Interpret your final decision. Problem 1i At a 1% level of significance, conduct a two-tailed test of hypothesis comparing the equality of two population means defined as follows. The first population mean relates to the mean of those values of Variable 4 that have the attribute represented by the "1" code for Variable 1. The second population mean relates to the mean of those values of Variable 4 that have the attribute represented by the "2" code for Variable 1. Do NOT use the pooled variance option when conducting this test and assume normal populations. In your Word solution file, under a subheading entitled Problem 1i, display all the steps using the 4 step P-value Approach. Copy and paste the Hypothesis Test results window from StatCrunch to your Word solutions file under the under Step 2 of the test. Interpret your final decision. Problem 1j In conducting the Two Population Means test in Problem 1i above, you made the assumption of not using the pooled variance option. At a 5% level of significance, test this assumption. In your Word solution file, under a subheading entitled Problem 1j display all the steps using the 4 step P-value Approach. Copy and paste the appropriate Hypothesis Test results window from StatCrunch to your Word solutions file under Step 2 of the test. Interpret your final decision. Problem 2 Problem 2a: Find the equation of the linear regression line relating Variable 6 and Variable 4 in your survey, based on the 20 pairs of sample data values you created for these two variables in Problem 1. Copy and paste the first screen of the Simple Linear Regression results window from StatCrunch to your Word solutions file under the subheading Problem 2a.Type the linear regression equation under the pasted Simple Linear Regression results window. Problem 2b: Based on the appropriate output displayed in the Simple Linear Regression Results window, what percent of the variation in the dependent variable is explained by the independent variable? Type your answer in the Word solutions file under the subheading Problem 2b. Appropriately Interpret your answer.
