Pleаse nоte thаt this questiоn cоnsists of eight pаrts. Show all your work. Just giving the answer without showing work may result in zero for the question. There is a dataset on “crime” and “edu” which gives characteristics of 84 medium-sized U.S. counties. The overall purpose for the data set is to analyze factors that predict crime. The variable “crime” is the crime rate reported per 100,000 residents last year. The variable “edu” is the percentage of individuals in the county having at least a high-school diploma. The researcher is interested in developing a regression model to predict the "crime" based on the "edu" using these data. Partial output of the regression analysis is provided below. Write down the least squares regression line for predicting the "crime" (crime rate reported per 100,000 residents last year) using the "edu" (percentage of individuals in the county having at least a high-school diploma). Interpret the slope parameter in the context of this problem. We want to see if there is convincing evidence that the "crime" (crime rate reported per 100,000 residents last year) decreases as the "edu" (percentage of individuals in the county having at least a high-school diploma) increases. Write the appropriate null and alternative hypothesis you would formulate to test this. Calculate the test statistic. Calculate the p value. You may use the table or MINITAB to find the final p value; however, you need to write the probability statement for the p-value for this test. Based on the p value you obtained, what can you say about this hypothesis? (You may use 5% significance level to make the conclusion.) What is the correlation between the "crime" (crime rate reported per 100,000 residents last year) and the "edu" (percentage of individuals in the county having at least a high-school diploma) ? What is the predicted "crime" (crime rate reported per 100,000 residents last year) when the "edu" (percentage of individuals in the county having at least a high-school diploma) is 71? Clearly show your work.
