To find the mean of the given list of numbers, follow these steps:
1. List the numbers given:
[tex]\[
17, 68, 35, 29, 90, 53, 65, 57, 54, 61, 97, 48, 79, 60, 18
\][/tex]
2. Count the total number of values:
There are 15 numbers in the list.
3. Calculate the sum of all the numbers:
[tex]\[
17 + 68 + 35 + 29 + 90 + 53 + 65 + 57 + 54 + 61 + 97 + 48 + 79 + 60 + 18
\][/tex]
4. Calculate the mean:
The mean is obtained by dividing the sum of the numbers by the count of the numbers.
Therefore, with the provided data:
The mean value [tex]\(= 55.4\)[/tex]
