c.
Comparison of credits at time of graduation for randomly chosen accounting and economics students:
xbar= 139, s1 = 2.8, n1 = 12, xbar2= 137, s2 = 2.7, n2 = 17, α = .05, right-tailed test.

For each solve:
Degrees of Freedom (df)
Standard Error (SE)
t-calculated (t-calc)
P-value
t-critical (t-crit)
