The pulse rate of 11 people was measured before and after going on a new thrill ride at the park. A researcher wants to determine if the pulse rate "after" is significantly more than the pulse rate "before". The results are shown. Using a significance level of .05, is the pulse rate after significantly more than the pulse rate before?

Subject	Before	After
1	85	85
2	79	84
3	73	87
4	76	84
5	75	83
6	79	92
7	74	77
8	67	71
9	80	76
10	69	84
11	71	80

Please show your work by hand and when you are using a ti 84, please say brief steps on how you did it (I am very familiar with one). Thanks!
