Answer:
The correct value is t* = 2.797.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a two-tailed confidence level of 
. So we have T = 2.797.
You do 3832083082x 32u393829832983x to get this 5,418
There is a pattern of 8 after each number (b)
For 8, it's 6.2 . For 9, it's 7.0 (or 7)
