Question

So in lab last week, we did an experiment about pre and post-exercise measurements. One of those measurements was heart rate. We had to develop null hypothesis (done), and compute t-values (done as well). Our degree of freedom was 18 (19-1). I need help finding P-values in order to accept or reject the null hypothesis. What are the p-values for the following t-values? (all degree of freedoms are 18). It was a two tailed t-test.

The t-values were:

Heart rate: 5.021765

Oral Temp.:-3.497

Ear Temp.: -4.300546583
