Answer :

Final answer:

The 90th percentile of the given data is 124 minutes.

Explanation:

In order to find the 90th percentile, you need to organize the data in ascending order. The given data in this question is: 45, 99, 108, 116, 118, 118, 118, 119, 120, 121, 124, 130, and 148. Since we have 13 values, the 90th percentile will be the value at the 90th percentile rank, which is 90% of 13. 90% of 13 is 11.7, which rounds up to 12. So, the 90th percentile is the 12th value in the ordered list, which is 124 minutes.
