Step 1
The formula for degrees of freedom in an independent-samples t-test is df = n1 + n2 - 2. Here, n1 = 25 and n2 = 35. So, df = 25 + 35 - 2 = 58. Show more…

(a) n = 20 for a one-independent sample t-test (b) df1 = 12, n2 = 19 for a two-independent sample t-test (c) critical value = 63.657 for a two-tailed test, α = 0.01 (d) critical value = 1.645 for a one-tailed test, α = 0.05
