Question

Please do parts c, d, and e (from the second picture) using the information from problem 5 ( the first picture). Thank you so much! 5. If you complete all six pages on all 16 homework assignments (ignoring HW1) this term, you will have worked 96 sides of statistics problems. Add on the two midterms (4 sides each) and final (usually 8 sides) and this gives 112 sides of problems in roughly 10 weeks! You might be curious how the number of pages of work in a course (xaxis) relates to the average self-reported amount learned by students (y axis) a. Suppose you collected data (number of pages of work assigned, average amount learned as reported by students) on many different classes at UCSD. Give a reason why the scatterplot of these data might resemble a function that increases and then decreases b. Suppose that the increasing part of the scatterplot follows the picture below Learning vs. Amount of Homework in Several Courses 20 40 80 100 120 Num pages assigned in course Estimate three things using this picture: The correlation, the slope of the regression line, and the y intercept of the regression line. What are the units on each idea?

Explanation / Answer

Conclusion:

i) Scatter plot obtained is very different from plot in (b) .plot in plot shows positive correlation with high correlation coefficient but for given that in (C) it can observed that there is no correlation between x and y

ii) correlation in (c) and std error in (d) have same result that we get from (e)
