Given the following sample sizes, determine the df. n1 = 18 and n2 = 22

3. Given the following sample sizes, determine the df. n1 = 40 and n2 = 40

n1 = 18, n2 = 22
df = ?
df = n1 + n2 - 2
df = 18 + 22 - 2
df = 40 - 2
df = 38

3) n1 = 40, n2 = 40
df = ?
df = n1 + n2 - 2
df = 40 + 40 - 2
df = 80 - 2
df = 78
