Is this supposed to be a matching game of some sort? If so, I don’t think any of these here match what’s in the tables.

One way to solve:
960-12x=816
144=12x

Another way to solve
80-x=68
x=12
Answer:
The t-value is 2.0049.
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 = 55 - 1 = 54
Now, we have to find a value of T, which is found looking at the t table, with 54 degrees of freedom(y-axis) and a confidence level of 0.95(
). So we have T = 2.0049
The t-value is 2.0049.
