Answer 1

Estimate of the population proportion
`\mathbf{\widehat{(P)}}` = 0.147

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
`\boldsymbol{\widehat{P} = (x)/(n)}`

=
`(1157)/(7831)`

= 0.147
