Olin [163]

Answer:

1329.85≤μ≤1330.14

Step-by-step explanation:

z score for 99% confidence interval

from the z table we can find that the score for 99% confidence is 2.58

formula

z=\frac{x-μ}{[tex]\frac{{σ}[tex]\sqrt{n}}[/tex]}[/tex]

where

x-sample mean

μ-population mean

σ-population standard deviation

n-sample size

2.58=\frac{1330-μ}{[tex]\frac{{442}[tex]\sqrt{24}}[/tex]}[/tex]

1330-2.58×24÷442≤μ≤1330+2.58×24÷442

1329.85≤μ≤1330.14
