There is a construction zone on the highway. The speeds of vehicles passing through this construction zone are normally distributed with a mean of 49 mph and a standard deviation of 4 mph. Suppose that you want to make a speed limit such that only about 10% of the vehicles passing through this zone exceed the speed limit. What should the speed limit (rounded to the nearest integer) ?

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
