Step-by-step explanation:

There is not only one curve for t - student distribution, but 30

The t - student distribution curve is more wide the two tails have much more values than in the normal curve distribution.

Each curve in t-student distribution correspond to one specific degree of freedom. The curve t-student will become closer in shape to the curve of normal distribution as the degrees of freedom are growing till the become the same when n = 30
