Question 1 3.125 points For the linear regression equation y-3x+1 and y-number of pizza slices and x-number of final exams a student has, what is the correct interpretation of 3? For every 1 final exam that a student has, they eat 3 more slices of pizza, on average For every 1 pizza slice a student eats, they have to take 3 more final exams, on average. For every 3 pizza slices a student eats, they have to take an additional final exam, on For every 3 final exams a student has, they eat 4 slices of pizza more, on average 3.125 points Question 2 A marine transportation company would like to know which economic efficiencies (measured as quantitative numbers) are related (positive or negative) to number of organizations within an industry (also measured as quantitative numbers). Which of the following would be an appropriate test to check this hypothesis? Mauchly's test of sphericity One-sample t-test Chi-square test 3.125 points Sav Question 3 in ground effect (0GD) hover ceiling. Both of these measures are quantitative. Which statistical test would look at this relationship? Poisson Regression t-test Chi-square Save and Submit

Explanation / Answer

1)As 3 is the slope of the line of the given regression equation,it implies that with increase in 1 unit of x, y increases by 3 units.

Thus, for every 1 final exam that a student has, they eat 3 more slices of pizza, on average.

2) In this case, Pearson correlation test would be an appropriate test to check the hypothesis as positive or negative relation is to be established.

3) In this case, One sample t-test would look at this relationship.
