Please answer all parts a. - c.

Thanks!

Use the following sample data for variables y and x to complete parts a through c. 110 83 121 129 117 80 107 123 78 4 3 5 6 4 3 4 6 2 a. Develop a scatter plot for these data and describe what, if any, relationship exists b. (1) Compute the correlation coefficient. (2) Test to determine whether the correlation is significant at the significance level of 0.05. Conduct this hypothesis test using the p-value approach. (3) Compute the regression equation based on these sample data c. Test the significance of the overall regression model using a significance level equal to 0.05. a. Choose the correct graph below. O A. O B. O C. OD. 150- Ay 150 Q 150- Q 150 There appears to be linear relationship between x and y. b. Compute the correlation coefficient r. =(Round to three decimal places as needed.) Test to determine whether the correlation is significant at the significance level of 0.05. First determine the null and alternative hypotheses that are to be tested. O A. Ho PSO, Ha P> 0 OB. Ho p20, Ha: P0 Now find the p-value. p-value = (Round to three decimal places as needed.) Determine the appropriate conclusion at the significance level of 0.05. Choose the correct answer below. O A. Reject the null hypothesis. There is not sufficient evidence to conclude that the correlation is significant. Click to select your answer(s) and then click Check Answer. All parts showc. lest the significance of the overall regression model using a significance level equal to 0.05. O A. Reject the null hypothesis. There is not sufficient evidence to conclude that the correlation is significant. O B. Do not reject the null hypothesis. There is not sufficient evidence to conclude that the correlation is significant. O C. Reject the null hypothesis. There is sufficient evidence to conclude that the correlation is significant. O D. Do not reject the null hypothesis. There is sufficient evidence to conclude that the correlation is significant. Compute the regression equation based on these sample data and interpret the regression coefficients. Let x be the independent variable and determine the estimated regression equation for the predicted values of y. y = [+()x (Round to two decimal places as needed.) c. What are the appropriate hypotheses to test the significance of the overall regression model? O A. Ho: B1 2 0 OB. Ho B. =0 HA B,SO HA B, #0 OC. Ho: B, SO OD. Ho: B, $0 HA B1 20 HA B, =0 OE. Ho: B1 50 OF HO B, 20 HA B1 20 HA BI CO Calculate the simple linear regression test statistic t. =(Round to two decimal places as needed.) Now find the p-value p-value = (Round to three decimal places as needed.) Since the p-value is than a , the null hypothesis. Conclude that the regression model significant. This means that knowing x useful help in predicting y. Click to select your answer(s) and then click Check Answer. All parts
