Additionally, provide a comparison of User Ratings between the two genres (e.g., does one genre outperform the other in terms of User Ratings). if you desire, you can show any moth work you wont within the short answer textbox. Enter your answer here Q3 Problem 2 13 Points Researchers collected data on percent body fat, age, weight, height, and 10 body circumference measurements for 252 adult males. Researchers are interested in creating a model to predict percent body fat from abdomen circumference (measured in cm). The correlation between these two variables is calculated to be 0.8137; a scatterplot of these variables is provided below. Additionally, the means and standard deviations for these two variables are provided below. Mean Standard Deviation Percent Body Fat (%) 18.94 7.7509 Abdomen Circumference (cm) 92.556 10.7831 Scatterplot of Abdomen Circumference and Percent Bodyfat 40 30 Percent Bodyfat 20 10 70 80 90 100 110 120 130 140 150 Abdomen Circumference (cm) Q3.1 Problem 2 A 5 Points Based on the scatter plot and the correlation coefficient (r = 0.8137), would least squares regression be appropriate to predict percent body fat from abdomen circumference? Using the correlation coefficient and the provided scatter plot, describe the form, direction, strength, and outliers. ( Make sure to answer the question as well as describing the relationship.)
