The table below show data that has been collected from different fields from various farms in a certain valley. The table contains the grams of Raspberries tested and the amount of their Vitamin C content in mg. Find a linear model that express Vitamin C content as a function of the weight of the Raspberries. grams Vitamin C content in mg 45 7.4 55 11.8 65 16.4 75 21 85 24.7 95 29.5 105 33.6   A)  Find the regression equation:     y=y= x+x+   Round your answers to 3 decimal places   B)  Answer the following questions using your un-rounded regression equation.   If we test 135 grams of raspberries what is the expected Vitamin C content?   mgmg (round to the nearest tenth)

The data show the chest size and weight of several bears. Find the regression equation, letting chest size be the independent (x) variable. Then find the best predicted weight of a bear with a chest size of 58 inches. Is the result close to the actual weight of 672 pounds? Use a significance level of 0.05. Chest size (inches) Weight (pounds) 46 57 53 41 40 40 384 580 542 358 306 320

Prehistoric pottery vessels are usually found as sherds (broken pieces) and are carefully reconstructed if enough sherds can be found. Information taken from Mimbres Mogollon Archaeology by A. I. Woosley and A. J. McIntyre (University of New Mexico Press) 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 Constant -0.221 2.429 -0.09 0.929 Diameter 0.8067 0.1524 5.33 0.001 S = 4.23750 R-Sq = 87.5% (a) The standard error S. of the linear regression model is given in the printout as "S." What is the value ofS,? e (b) The standard error of the coefficient of the predictor variable is found under "SE Coef." Recall that the standard error for b is SJVEX² - (1/n)(Ex). From the Minitab display, what is the value of the standard error for the slope b? (c) The formula for the margin of error E for…
