question 33

Multiple Choice

The following MINITAB output display presents the results of a hypothesis test on the difference between two proportions. Test and CI for Two Proportions: P1, P2
$\begin{array}{lccc}\text { Variable } & \mathrm{X} & \mathrm{N} & \text { Sample P } \\\text { P1 } & 56 & 94 & 0.595745 \\\mathrm{P} 2 & 34 & 72 & 0.472222\end{array}$

Difference $= p ( \mathrm { P } 1 ) = p ( \mathrm { P } 2 )$
Estimate for differenc 0.123523
$95 \%$ CI for difference: $( - 0.02941,0.276456 )$
T-Test of difference $= 0 ($ vs not $= \mathbb { 0 } ) :Z = 1.583084 \mathrm { P }$ -Value $= 0.113402$ Is this a left-tailed test, a right-tailed test, or a two tailed test?
