A busy traffic intersection in a city was experiencing an average of 20 accidents per week. The council decided to try to reduce the number of accidents by placing a stop sign at the intersection. In this situation, what is: a. the null hypothesis
b. the alternative hypothesis

Null hypothesis; H0: μ1 = μ2

Alternative hypothesis; Ha: μ1 > μ2

Step-by-step explanation:

We are told that the telraffic was experiencing an average of 20 accidents per week.

Thus, μ = 20

We are told that the council decided to try to reduce the number of accidents.

Thus defining the hypothesis, we have;

Null hypothesis; H0: μ1 = μ2

Alternative hypothesis; Ha: μ1 > μ2

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
