Answer:
Estimate of the population proportion [tex]\mathbf{\widehat{(P)}}[/tex] = 0.147
Step-by-step explanation:
Given -
Wiley Publications has determined that out of a sample of 7,831 of its publications for 2012, 1,157 of them had been pirated online in some form.
Let x be the no of publication had been pirated online in some form.
x = 1157
n = 7831
Population proportion [tex]\boldsymbol{\widehat{P} = \frac{x}{n}}[/tex]
= [tex]\frac{1157}{7831}[/tex]
= 0.147
