brilliants [131]

Solution: The 90% confidence interval for the population mean is:

\bar{x} \pm t_{\frac{0.1}{2}} \frac{s}{\sqrt{n}}

Where:

\bar{x}=2.71

s=\sqrt{0.25} =0.5

t_{\frac{0.1}{2}}=1.729 is the critical value at 0.1 significance level for df = n-1 =20-1=19

2.71 \pm 1.729 \frac{0.5}{\sqrt{20}}

2.71 \pm0.19

\left( 2.71-0.19,2.71+0.19\right)

\left(2.52,2.90 \right)

Therefore, the 90% confidence interval for the population mean is \left(2.52,2.90 \right)
