Assume That You Plan to Use a Significance Level Of \alpha

question 125

Multiple Choice

Assume that you plan to use a significance level of $\alpha = 0.05 \text { to test the claim that } \mathrm { p } _ { 1 } = \mathrm { p } _ { 2 }$ . Use the given sample sizes and
numbers of successes to find the z test statistic for the hypothesis test.
- $$\begin{array} { l l } \mathrm { n } _ { 1 } = 124 & \mathrm { n } _ { 2 } = 119 \\\mathrm { x } _ { 1 } = 51 & \mathrm { x } _ { 2 } = 43\end{array}$$

• A) \(z = 8.951\)
• B) \(z = 0.799\)
• C) \(z = 0.395\)
• D) \(\mathrm { z } = 16.623\)
