Show work please, Thanks!
Question 3: The regression line equation for a set of data is given by y-hat = 2.3x+5 with n = 10. The mean value of y is 10.1 for the data set. Use a = 0.05. A. If the linear correlation coefficient is r=0.521, what is the best predicted y-value for x = 5? Justify for your answer. B. If the linear correlation coefficient is r = 0.972, what is the best predicted y-value for x...

The answer key says 12.75, but Im not sure why? I believe it
is y = 3(4.3) which is 12.9. Unless the key is wrong? Thank
you.
29) Use the given data to find the best predicted value of the response variable. 29) Four pairs of data yield r = 0.942 and the regression equation y = 3x. Also, y = 12.75. What is the best predicted value of y for x = 4.3?

1. The data in Table 3.3 are a subset of the data obtained by Kaneto, Kosaka, and Nakao (1967). The experiment investigated the effect of vagal nerve stimulation on insulin secretion. The subjects were mongrel dogs with varying body weights. Table 3.3 gives the amount of immunoreactive insulin in pancreatic venous plasma just before stimulation of the left...

You run a regression analysis on a bivariate set of data (n = 108). With z = 27.5 and у = 67.4, you obtain the regression equation y 0.488z 33.947 with a correlation coefficient of r = 0.076. You want to predict what value (on average) for the response variable will be obtained from a value of 150 as the explanatory variable. What is the predicted response value?...
