Answer:
0.75
the reason is because if we round it to the nearest tenth . 0.75 becomes 0.8. and 0.075 becomes 0.1 . 0.8 is 8/10th of 1. 0.1 is 1/10th of 1. therefor 0.8 is bigger
Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.
To find the percent, we first need the z-score.
(15 - 13.5) / 7.3 = 0.21
Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.
To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
