question 79

Multiple Choice

To perform a hypothesis test of two population proportions, the pooled estimate of $p$ must be determined. The pooled estimate, $\hat { p }$ , is

• A) \(\hat { p } = \frac { x _ { 1 } + x _ { 2 } } { n _ { 1 } + n _ { 2 } }\)
• B) \(\hat { \mathrm { p } } = \frac { \mathrm { x } _ { 1 } } { \mathrm { n } _ { 1 } } + \frac { \mathrm { x } _ { 2 } } { \mathrm { n } _ { 2 } }\)
• C) \(\hat { p } = \frac { n _ { 2 } x _ { 1 } + n _ { 1 \times 2 } } { n _ { 1 } + n _ { 2 } }\)
• D) \(\hat { p } = \frac { x _ { 1 } + x _ { 2 } } { n _ { 1 } n _ { 2 } }\) 3 Construct and interpret confidence intervals for the difference between two population proportions.
