Alligators perform a spinning​ maneuver, referred to as a​ "death roll," to subdue their prey. In a study of alligator death​ rolls, one of the variables measured was the degree of the angle between the body and head of the alligator while performing the roll. A sample of rolls yielded the data provided​ below, in degrees. At the ​% significance​ level, do the data provide sufficient evidence to conclude​ that, on​ average, the angle between the body and head of an alligator during a death roll is greater than ​? ​(Note: and s. Preliminary data analyses indicate that you can reasonably use a​ t-test to conduct the hypothesis​ test.)
