Use the provided contingency table and expected frequencies. At a = 0.05, test the hypothesis that the
variables are independent. Complete parts (a) through (e) below.
19 (22.568)
224 (220.432)
Injury
24 (20.432)
No injury
196 (199.568)
(a) Identify the claim and state Ho and Ha.
Họ: An athlete's injury result is independent of whether or not the athlete has stretched.
Ha: An athlete's injury result is dependent on whether or not the athlete has stretched.
Which hypothesis is the claim?
Alternative hypothesis
V Null hypothesis
(b) Determine the degrees of freedom, find the critical value, and identify the rejection region.
Calculate the degrees of freedom.
d.f. = 1
(Type a whole number.)
Find the critical value.
xổ =0
(Round to three decimal places as needed.)
Transcribed Image Text:(Rõund to three decimal places as needed.)
Which region below is the correct rejection region?
OA. s-xổ or y? zx%
O B. x?<x3
C. 2>xổ
(c) Calculate the test statistic.
%3D
(Round to three decimal places as needed.)
(d) Decide whether to reject or fail to reject the null hypothesis.
Fail to rejectH, because the test statistic is not in the rejection region.
(e) Interpret the decision in the context of the original claim.
There is not enough evidence at the 1% level of significance to reject` the claim that
an athlete's injury result is independent of whether or not the athlete has stretched.
