Question

How do you do these 4 questions and the reasons?

Answer 1

Step-by-step explanation:

"There are several flights that have very long delays."

True.  On the boxplot, we can see several outliers greater than the maximum.

"More than 25% of flights are either exactly on time or arrive early."

False.  According to the 5 number summary, 25% of the flights are between -55 and 13.  So less than 25% of the flights are on time or early.

"About 50% of flights are delayed between 13 and 35 minutes."

False.  According to the 5 number summary, 25% of the flight times are less than 13 minutes, and 50% of the flights are less than 35 minutes.  So 25% of the flights are delayed between 13 and 35 minutes, not 50%.

"About 25% of flights are delayed by more than 78 minutes."

True.  According to the 5 number summary, 75% of the flights are delayed less than 78 minutes.  Which means 25% of the flights are delayed more than 78 minutes.
