# Evaluating the effectiveness of stem cell treatment (cont.)

Conduct the hypothesis test and compute the p-value for evaluating whether there is a difference between the mean heart pumping capacities of sheep's hearts in the control and treatment groups.

Since we're testing for a difference, the order in which we subtract matters. We can specify it using the `order`

argument in the `calculate()`

function. For example, to achieve `group1 - group2`

use `order = c("group1", "group2")`

.
