Question 260849: Find the p-value:
Comparison of average commute miles for randomly chosen students at two community colleges:
¯ x1 = 15, s1 = 5, n1 = 22, ¯ x2 = 18, s2 = 7, n2 = 19, α = .05, two-tailed test.

You can put this solution on YOUR website! Find the p-value:
Comparison of average commute miles for randomly chosen students at two community colleges:
- x1 = 15, s1 = 5, n1 = 22,
¯ x2 = 18, s2 = 7, n2 = 19,
α = .05, two-tailed test.
--------------------------------
p-value = 2*P(t< - 1.5564 with df = 22+19-2 = 39) = 2*0.0638.. = 0.1276..
=========================================================
The TI-84 says the p-value is 0.12944....
because it uses df = 32.0275...
=========================================================
