Homework Statement
There's no need to write out the full question, but basically we have 6 diets, and for each one a list of the levels of protein in 10 independant samples for each. Sample mean and standard deviation given.
Calculate and interpret a confidence interval centered on the sample mean for diet one.
Homework Equations
The Attempt at a Solution
The sample mean for diet 1 is 100, SD is 15.1
When it says a confidence interval centered on this, do i just calculate
100+-t*(15.1)/root(10) where t* is the critical value obtained using a t distribution with n-1 = 9 degrees of freedom?
