The answer is d. Look at the equation , there isn’t a line under the > sign, so you don’t need to pick the graph with a colored circle, and then there are 3 left that are not colored. Those are b,c and d. Now, the > sign does to the right ( the pointy part) so your line had to go to the right. Only d is like that. Hope this helps and can you make me brainliest?

A driving school wants to find out which of its two instructors is more effective at preparing students to pass the state’s driv

Answer:

Yes, there is evidence to support that claim that instructor 1 is more effective than instructor 2

Step-by-step explanation:

We can conduct a hypothesis test for the difference of 2 proportions. If there is no difference in instructor quality, then the difference in proportions will be zero. That makes the null hypothesis

H0: p1 - p2 = 0

The question is asking whether instructor 1 is more effective, so if he is, his proportion will be larger than instructor 2, so the difference would result in a positive number. This makes the alternate hypothesis

Ha: p1 - p2 > 0

This is a right tailed test (the > or < sign always point to the critical region like an arrowhead)

We will use a significance level of 95% to conduct our test. This makes the critical values for our test statistic: z > 1.645.

If our test statistic falls in this region, we will reject the null hypothesis.
