Question:

A study rated various brands of peanut butter on how creamy they were. The study used 4 different brands, found a sample mean of 17, and a sample standard deviation of 1.

We wish to construct a 99% confidence interval for these findings.

How many degrees of freedom do we have?
To construct this confidence interval, what type of test should we use?1, 2, or 3 tail t test
If we wish to use an alphaalpha of 0.01, the value of t_crit is
Calculate Calculate X_+(sX_)(tcrit) using only the positive value of t_crit.
How do we present our confidence interval?
