You and your friend are conducting research regarding a sample of 200 students, she or he says that you need to use only the t test, you disagree. Explain your position.
What will be an ideal response?
Since the sample size is 200 students, then a frequency table can be made and we can find the standard error of the mean; therefore, we would use a z test. A t test is only used when the population is small and the standard error of the mean is unknown. Therefore, it would be inappropriate to use the t test.
