Students in a high school mathematics class decided that their term project would be a study of
the strictness of the parents or guardians of students in the school. Their goal was to estimate the
proportion of students in the school who thought of their parents or guardians as "strict". They do
not have time to interview all 1,000 students in the school, so they plan to obtain data from a sample
of students.

The parameter of interest in this scenario is the proportion of all 1,000 students within the school who have "strict" parents or guardians.

How to calculate a test statistic?

In Mathematics, the test statistics of a given sample is calculated by using this formula:

[tex]Z=\frac{x\;-\;u}{\frac{\sigma}{\sqrt{n} } }[/tex]

Where:

  • x is the sample mean.
  • u is the mean.
  • is the standard deviation.
  • n is the sample size.

In conclusion, a possible test statistic which can be used to estimate this parameter is the proportion of all students who have "strict" parents or guardians, based on the collected sample.
