T Test Vs Z Test. We can calculate the t statistics by the given formula. However you need to check that np 0 and n 1 p 0 are both greater than 10 where n is your sample size and p 0 is your hypothesized population proportion.
T x1 x2 σ n1 σ n2. A t test is used when parameters like the standard deviation of the population are not known. The dataset can be downloaded from here.
We perform a one sample t test when we want to compare a sample mean with the population mean.
We perform a one sample t test when we want to compare a sample mean with the population mean. A t test is used when parameters like the standard deviation of the population are not known. Proportion problems are never t test problems always use z. The t test is based on student s t distribution.
