Final answer:
The value of the sample mean is approximately 50.445.
Explanation:
To calculate the sample mean, we need to add up all the values in the data set and divide the sum by the number of data points. In this case, we have the following data:
30.0, 4.4, 33.1, 66.7, 81.5, 22.2, 40.4, 16.4, 73.7, 36.6, 109.9
Adding up all these values, we get:
30.0 + 4.4 + 33.1 + 66.7 + 81.5 + 22.2 + 40.4 + 16.4 + 73.7 + 36.6 + 109.9 = 554.9
Now, we divide this sum by the number of data points, which is 11:
554.9 / 11 = 50.445
Therefore, the value of the sample mean is approximately 50.445.
