Assume that you plan to use a significance level of ? = 0.05 to test the claim that p1 = p2. Use the given sample sizes and numbers of successes to find the z test statistic for the hypothesis test.
-In a vote on the Clean Water bill, 48% of the 205 Democrats voted for the bill while 42% of the 230 Republicans voted for it.

A) $z = 1.382$
B) $z = 0.754$
C) $z = 1.256$
D) $z = 1.068$

The Answer of Assume that you plan to use a significance level of ? = 0.05 to test the claim that p1 = p2. Use the given sample sizes and numbers of successes to find the z test statistic for the hypothesis test.
-In a vote on the Clean Water bill, 48% of the 205 Democrats voted for the bill while 42% of the 230 Republicans voted for it.

A) $z = 1.382$
B) $z = 0.754$
C) $z = 1.256$
D) $z = 1.068$

Assume That You Plan to Use a Significance Level of z=1.382z = 1.382z=1.382

Assume That You Plan to Use a Significance Level of $z = 1.382$
