The value of To from the t table will be 2.131

How to get the value?

The following can be deduced from the information:

P(-t0 < t < t0) = 0.95

2*P(t < t0) - 1 = 0.95

P(t < t0) = 0.975

df = 15

From t-table (column 1-0.975 = 0.025) in the row 15. Therefore, t0 = 2.131.

In conclusion, the answer is 2.131.
