For traffic that flows on a highway, the headway is the average time between vehicles. on four-lane highways, the probability p (as a decimal) that the headway is at least t seconds when there are 500 vehicles per hour traveling one way is given by p = 0.87t. under these circumstances, what is the probability that the headway is at least 15 seconds?

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
