Why does t-distribution have (n-1) degree of freedom?

WebTo find this value, we need the significance level (α = 0.05) and the degrees of freedom. The degrees of freedom (df) are based on the sample sizes of the two groups. For the body fat data, this is: $ df = n_1 + n_2 - 2 = 10 + 13 - 2 = 21 $ The t value with α = 0.05 and 21 degrees of freedom is 2.080. WebDetermine the probability that an observation from the Student's t distribution with degrees of freedom 99 falls on the interval [10 Inf]. p1 = 1 - tcdf (10,99) p1 = 0. tcdf (10,99) is nearly 1, so p1 becomes 0.
