P-value in a two-sample t test

A sociologist studying fertility in the United States and Canada wanted to compare how many babies, on average, women in each country have. The sociologist obtained a random sample of $88$‍ women from each country. Here is a summary of the number of babies for the women in each sample:

They want to use these results to test ${\text{H}}_0\text{: }{\mu }_{\text{US}}-{\mu }_{\text{C}}=0$‍ versus ${\text{H}}_{\text{a}}\text{: }{\mu }_{\text{US}}-{\mu }_{\text{C}}\ne 0$‍. Assume that all conditions have been met.
