Explanation In the Null hypothesis, generally the already proven fact is taken as the alternative hypothesis, while the opposite condition is taken as the Null hypothesis. Considering this, null and alternative hypothesis assumed in this case are as follows: a) Null Hypothesis- H0: Percentage of the delayed United flights ≥ the national average of 18% Alternative Hypothesis- H1: Percentage of the delayed united flights < the national average of 18% b) The two possible outcomes: 1. Rejection of Null Hypothesis: It means there are evidences that the Percentage of the delayed United flights is less than the national average of 18% 2...

Describe a three step process you choose to determine how many elementary schools there are in the city of 5 million people.

A circle of radius r centered at the point (0,r) in the plane will intersect the y-axis at the origin and the point A=(0,2r), as pictured below. A line passes through the point A and the point C=(11/2,0) on the x-axis. In this problem, we will investigate the coordinates of the intersection point B between the circle and the line, as 1 → ∞ A=(0,2r) B (0,0) (a) The line through A and C has equation: y= 2 117 x+27 (b) The x-coordinate of the point B is 4472 121,2 +4 40 (c) The y-coordinate of the point B is +27 121 44 (d) The limit as r→ ∞ of the x-coordinate of B is 121 (if your answer is oo, write infinity).
