a bus route takes about 45 minutes. the company's goal is mad of less than 0.5 minute. one drivers times for 9 runs of the route. did the driver meet the goal?44.2 , 44.9 , 46.1, 45.8 , 44.7 , 45.2 , 45.1 , 45.3, 44.6

Answer 1

The driver meet the goal

Step-by-step explanation:

We are given that a bus route takes about 45 minutes

If companys goal is made less than 0.5minute, then, the company's goal is 45 - 0.5 = 44.5minutes

If one drivers times for 9 runs of the route, as ahown;

44.2 , 44.9 , 46.1, 45.8 , 44.7 , 45.2 , 45.1 , 45.3, 44.6

We will have to calculate the mean data first as shown;

Mean time = 44.2 +44.9+46.1 +45.8+ 44.7+ 45.2+45.1+45.3+44.6/9

Mean time = 405.9/9

Mean time = 45.1minutes

Since the mean time(45.1minutes) is greater than the company's goal (44.5minutes), hence the driver meet the goal
