Find the critical value t, for the confidence level c = 0.95 and sample size n = 7 (Round to the nearest thousandth as needed.)

Since you say confidence level, you are implying a two-tailed test.

Confidence = 95 % means 100-95 % = 5% is outside the range.

So a two-tailed Alpha = 0.05

One-sided equivalent is from 2.5 to 97.5 % (95 in the middle).
