meriva

Answer: The value of test statistic = -10.67

Step-by-step explanation:

Test statistic for proportion:

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

, where p= population proportion

n= sample size

\hat{p} = sample proportion

AS per given,

p=0.94, n= 1004, \hat{p}=0.86

z=\dfrac{0.86-0.94}{\sqrt{\dfrac{0.94(1-0.94)}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{\dfrac{0.0564}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{0.0000561752988048}}\\\\=\dfrac{-0.08}{0.00749501826581}\\\\=-10.673756509\approx-10.67

i.e. the value of test statistic = -10.67
