Question 1182682: Salaries of 48 college graduates who took a statistics course in college have a mean, x, of $63,400. Assuming a standard deviation, σ, of $17,348, construct a 95% confidence interval for estimating the population mean μ.
$__ < μ <$__ (Round to the nearest integer as needed.) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! half-interval is z(0.975)*sigma/sqrt(n)
=1.96*17348/sqrt(48)
=$4907.78
the interval is ($58,492, $68,308)
or $58492 < mu < $68308
