Select the correct answerFind median and mode of the messages received on 9 consecutive days 15, 11, 9, 5, 18, 4, 15, 13, 17.Options18, 1513, 1813, 615, 16

To find the median and mode of the messages received on 9 consecutive days, we first need to understand what these terms mean.

The median is the middle number in a sorted, ascending or descending, list of numbers.

The mode is the number that appears most frequently in a data set.

Given the data set: 15, 11, 9, 5, 18, 4, 15, 13, 17

First, we need to sort the data set in ascending order: 4, 5, 9, 11, 13, 15, 15, 17, 18

The median is the middle number, which is 13 in this case.

The mode is the number that appears most frequently, which is 15 in this case as it appears twice.

So, the correct answer is 13, 15.
