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 20 rolls yielded the data provided below, in degrees. At the 10% 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 47°? (Note: x=48.48° and s=11.618°. Preliminary data analyses indicate that you can reasonably use a t-test to conduct the hypothesis test.) H0: μ is what? Ha: μ is what?

Question
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
20
rolls yielded the data provided below, in degrees. At the
10%
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
47°?
(Note:
x=48.48°
and
s=11.618°.
Preliminary data analyses indicate that you can reasonably use a t-test to conduct the hypothesis test.)
H0:
μ is what?
Ha:
μ is what?
