Can you please help me? I have the following information calulated but I am still lost.

n=12

x=4338.917

s=394.3707

Thank you.

n=12

x=4338.917

s=394.3707

z for 99% confidence interval = 2.575

First we need to calculate the standard error ,

SE = (z * s) / sqrt(n)

= (2.575 * 394.3707) / sqrt(12)

=293.1509

Therefore confidence interval = ( mu - SE , mu + SE )

= ( 4338.917 - 293.1509 , 4338.917 + 293.1509 )

= ( 4045.7 ,4632.1 ) Answer
