Answer: ($141,775, $158,225)

Step-by-step explanation:

Given : Significance level : $\alpha: 1-0.9=0.1$

Critical value : $z_{\alpha/2}=1.645$

Sample size : n= 49

Sample mean : $\overline{x}=150,000$

Standard deviation : $\sigma=35,000$

The confidence interval for population mean is given by :_

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$= 150,000\pm (1.645)\dfrac{35000}{\sqrt{49}}\\\\\approx150,000\pm8225\\\\=(150,000-8225,150,000+8225)=(141,775,158,225)$

Hence,he 90% confidence interval for the average salary of a CFA charter-holder = ($141,775, $158,225)
