Answer:

B. Independent-samples t test

Step-by-step explanation:

The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.

Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.

Thus, the best test to use in this case will be the Independent-samples t test

An airplane flying at attitude of 32,000 feet descends at a rate of 1,300 feet per minute. If the plane descends for 15 minutes,
Furkat [3]
Since the plane descends 1,300 feet per minute it would descend 19,500 feet after 15 minutes (1,300 x 15 = 19,500) Subtract this from the plane's initial altitude 32,000 and the new altitude will be 12,500. (32,000-19,500=12,500)
