On your TI-83 or 84 graphing calculator,
1. Press STAT and move cursor to TESTS

read p = .088490361
Since the value of p is high (greater than the level of
significance, then we fail to reject H0.
Remember the poem:
If p is HIGH, H0 must FLY. (We do not reject H0)
If p is LOW, H0 must GO. (We reject H0)
