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 42"? (Note: X= 42.55" and s= 10.564". Preliminary data analyses indicate that you can reasonably use a t-test to conduct the hypothesis test.) Click here to view the data on alligator death rolls.

Can I get some help solving the test statistic
Transcribed Image Text:Alligators performa 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 42°? (Note: x= 42.55° and s = 10.564°. Preliminary data analyses indicate that you can reasonably use a t-test to conduct the hypothesis test.)
