(c) What is the critical value for this test of independence when using a significance level of a
= 0.05?
Critical Value: x²
(d) What is the correct conclusion of this hypothesis test at the 0.05 significance level?
There is sufficient evidence to support the claim that the row and column variables are
dependent.
O There is not sufficient evidence to warrant rejection of the claim that the row and
column variables are dependent.
O There is sufficient evidence to warrant rejection of the claim that the row and column
variables are dependent.
