spin [16.1K]

Answer:800

Step-by-step explanation:

Mean(\mu )=\$ 4300

and P(X>6140)=0.0107

P(X>x_0)=0.0107

P\left ( \frac{X-\mu }{\sigma}

P\left ( z

\frac{x-\mu }{\sigma}=InvNormal(0.9893)

Using Z table to get InvNormal(0.9893)=2.30

\frac{6140-4300}{\sigma}=2.30

\sigma =\frac{6140-4300}{2.30}=800
