scoray [572]

Answer: 2.46

Step-by-step explanation:

Formula for x-score is given by :-

Z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where \overline{x} = Sample mean , \mu= population mean, \sigma = population standard deviation, n= sample size.

As per given , n=10

\mu= $29,056

\sigma = $3,339

\overline{x} =  $31,650

Then,

z=\dfrac{ 31650-29056}{\dfrac{3339}{\sqrt{10}}}\\\\=\dfrac{2594}{\dfrac{3339}{3.16227766017}}\\\\=\dfrac{2594}{1055.88451073}=2.45670807142\approx 2.46

Hence, the z-score = 2.46
