Scatterplot of Time vs Year 280 270 260 250 240 230 220 210 1900 1920 1940 1960 1980 2000 Year Summary Statistics Variable N Mean StDev Minimum Maximum Time Year 24 227.821 14.554 212.320 273.200 24 1949.83 32.984 1896.00 2000.00 Question 2: Give the equation for this new line and compare it with the line you found for the whole dataset, commenting on the effect of the outlier. ***Note: You must remove the outlier from the data set. Question 3: Our least squares regression line associates years as an explanatory variable, with times in the 1,500 meter race as the response variable. Use the least squares regression line you found in question 2 to predict the 1500 meter time in the 2008 Olympic Games in Beijing. Comment on your prediction.Explanation / Answer
Dear student , Provided question is incomplete regression equation is missing. . I have provide you solution of question 2 with the correct equation.
Solution of question 2:
Regression equation is Y = 994.2 - 0.3930*Year
X = 2008
Y = 994.2 - 0.3930*2008
Y = 205.056
Predicted Time taken in 1500 m olympics is 205.056.
