Answer :
The student's conclusion is not appropriate or no, because there were not enough measurements to use standard deviation.
Given:
suppose a student repeats a measurement two times and then calculates the standard deviation. because the standard deviation is small, the student reports that their experiment was extremely precise.
standard deviation:
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
To find standard deviation :
σ = x - μ / z
But here sample mean and proportion , z score not given so there are not enough measurements to use standard deviation.
