In Microsoft Excel you can also use the t test two samples to mean unequal variance. So you can go into Microsoft Excel and go into Iris data set. So we go into data analysis in there we select a two samples you mean and covariance and we create Okay. Then we put in the first variable then we put in the second variable. We put in our labor's the hypothesized mean difference, we leave it as blank. So we came up with a new worksheet.

Washi and we create Okay, everywhere have the Result bodies t test assuming an equal variance so we have our degree of freedom t statistic and all these are p values.
