Concept explainers
To find: The standard error of the mean for the provided data set.
Answer to Problem T8.2SPT
The standard error of the mean is 16.07
Explanation of Solution
Given:
The weights of 3 males are 160, 195 and 215.
Formula used:
The formula to compute the standard error of mean is:
Where,
s is the sample standard deviation
The formula to compute the sample standard deviation is:
Calculation:
Here, mean can be calculated as:
Standard deviation can be calculated as:
Now, the standard error of the mean can be calculated as:
The standard error of the mean is 16.07.
Hence, the correct option is (d).
