Rachel drew the two graphs below. Graph R

On a coordinate plane, a line goes through points (0, 0) and (2, 1).
Graph S

On a coordinate plane, a line goes through points (0, 0) and (1, 2).

Rachel says that Graph R has a greater constant of variation than Graph S. Which statement explains whether Rachel is correct?

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
