Iteru [2.4K]

Part a
The sample size is large enough to use the central limit theorem because it is greater than 30.

Part b.
The mean of the sampling distribution is 62000.
The standard error is computed as
$SE=\frac{s}{\sqrt{n}}=\frac{27000}{\sqrt{100}}=2700$

Part c.
Compute for the corresponding z-score of more than 2700 from the population mean.
$z=\frac{2700}{2700}=1$

Therefore,
$P\left(z\ \textgreater \ 1\right)=0.1587$
