The computation of the data shows that the standard error is 0.015.
<h3>How to calculate the standard error?</h3>
From the information, the following can be deduced:
Number of students n = 49
Randomly selected students = 0.794
The standard error will be:
= 0.105/✓49
= 0.105/7
= 0.015
In conclusion, the standard error is 0.015.
