Using the data in Table 6–11, answer the following:a. What is the slope?b. What is the intercept?c. Write the regression equation.d. Calculate a regression forecast for month 25.

Applying the Concepts and SkillsIn Exercises, we repeat data from exercises in Section 14.2. For each exercise here,a. obtain the linear correlation coefficient.b. interpret the value of r in terms of the linear relationship between the two variables in question.c. discuss the graphical interpretation of the value of r and verify that it is consistent with the graph you obtained in the corresponding exercise in Section 14.2.d. square r and compare the result with the value of the coefficient of determination you obtained in the corresponding exercise in Section 14.3.Tax Efficiency. Following are the data on percentage of investments in energy securities and tax efficiency from Exercises. x 3.1 3.2 3.7 4.3 4 5.5 6.7 7.4 7.4 10.06 y 98.1 94.7 92.0 89.8 87.5 85.0 82.0 77.8 72.1 53.5

Prehistoric pottery vessels are usually found as sherds (broken pieces) and are carefully reconstructed if enough sherds can be found. Information taken from a study provides data relating x = body diameter in centimeters and y = height in centimeters of prehistoric vessels reconstructed from sherds found at a prehistoric site. The following Minitab printout provides an analysis of the data. Predictor Coef SE Coef T P Constant -0.233 2.429 -0.09 0.929 Diameter 0.7948 0.1671 5.33 0.001 S = 4.10980 R-Sq = 80.3%       (a) The standard error Se of the linear regression model is given in the printout as "S." What is the value of Se?   (b) The standard error of the coefficient of the predictor variable is found under "SE Coef." Recall that the standard error for b is  Se   Σx2 −  1 n (Σx)2 .  From the Minitab display, what is the value of the standard error for the slope b?
