Question 11 Consider the following bivariate data. X 46 44 52 53 39 48 53 51 49 47 Y 60 60 74 77 51 69 70 76 71 67 Use the regression line to estimate the value of y when x = 50 and comment on the reliability of this estimate. 1 y ? 39.3, the correlation is strong and this is an interpolation, so the estimate is reliable. 2 y ? 70.6, but the correlation is weak, so the estimate is not reliable. 3 y ? 70.6, the correlation is strong and this is an interpolation, so the estimate is reliable. 4 y ? 39.3, but this is an extrapolation, so the estimate is not reliable.

Question 4. (25 points) A simple linear regression of the form y = Β₀ + Β₁ X₁ applied to 17 (x,y) data points resulting in the values Β₀ = 6.54 and Β₁ = 1.23 for the y-intercept and slope, respectively. The standard error of the regression line sigma hat (̐̑) = 2.93, the variance of X = 2.60, and the variance of Y = 4.86. (Chapter 12) Note: Sxx = Var(X)*(n-1) and SYY = Var(Y)*(n-1) a) Given that the mean X = 2.8, what is the mean value of Y? b) What is the correlation r between X and Y? c) What is the R"-squared coefficient of determination for this regression line? d) Given that the t-statistic of the slope Β₁ equals 2.7 with 15 d.o.f., what is the F-statistic for this regression line? r = ̐Β₁ √(Sxx / SYY) so that the sample correlation coefficient is simply a scaled version of the estimated slope parameter ̐Β₁. Moreover, it turns out that r" = R" so that the square of the sample correlation coefficient is equal to the coefficient of determination of the regression model. This is because the F-statistic is the square of the t-statistic t" = F

The standard error of the regression line sigma hat (̂σ) = 2.93, the variance of X = 2.60, and the variance of Y = 4.86. (Chapter 12) Note: Sxx = Var(X)*(n-1) and Sုု = Var(Y)*(n-1) a) Given that the mean X = 2.8, what is the mean value of Y? b) What is the correlation r between X and Y? c) What is the R²-squared coefficient of determination for this regression line? d) Given that the t-statistic of the slope ̠₁ equals 2.7 with 15 d.o.f., what is the F-statistic for this regression line? r = ̢̠₁ √(Sxx / Sုု) so that the sample correlation coefficient is simply a scaled version of the estimated slope parameter ̢̠₁. Moreover, it turns out that r² = R² so that the square of the sample correlation coefficient is equal to the coefficient of determination of the regression model. This is because the F-statistic is the square of the t-statistic t² = F

Run a regression analysis on the following bivariate set of data with y as the response variable. Find the correlation coefficient and report it accurate to three decimal places. r = 0.924. What proportion of the variation in y can be explained by the variation in the values of x? Report answer as a percentage accurate to one decimal place. (If the answer is 0.84471, then it would be 84.5%...you would enter 84.5 without the percent symbol.) r^2 = 90%. Based on the data, calculate the regression line (each value to three decimal places). y = x +. Predict what value (on average) for the response variable will be obtained from a value of 61 as the explanatory variable. Use a significance level of alpha = 0.05 to assess the strength of the linear correlation. What is the predicted response value? (Report answer accurate to one decimal place.)
