Assume that a study of 500 randomly selected airplane routes showed that 482 arrived on time. Select the correct interpretation of the probability of an airplane arriving late. Interpret an event as significant if its probability is less than or equal to 0.05.
Answer: We are given that out of 500 randomly selected airplanes, 482 arrived on time.
Therefore, the probability of airplane being on time 
And the probability of airplane being late 
Since the probability of airplane being late is 0.036, which is less than 0.05, therefore the event is significant at 0.036

Answer:
4 bags
Step-by-step explanation:
The way to read a step and leaf diagram is to consider the "stem" as the tens digit and "leaf" ans the ones digit.
So "0" in stem and "5" in leaf would be the number "05" or simply "5"
Also, "2" in stem and "4" in leaf would be the number "24"
When we have more numbers in leaf, they are basically different numbers. So lets list the numbers from stem-and-leaf plot:
5, 24, 30, 34, 65, 70, 74, 87, 90
The question asks for how many numbers are there LESS THAN 40?
the numbers less than 40 are:
5, 24, 30, 34
That is 4 numbers
Answer:
23/25 and 92% missed
