A random sample is selected from an approximately normal population with an unknown standard deviation. Use the t distribution to find the p-value for the given sample size, T value, and test direction.

The onlinet distribution calculator will be very handy.

Round your answers to 3 decimal places as necessary.

1. n = 10,T = 0.34, one-tailed (upper): p =
2. n = 8,T = 2.6, one-tailed (upper):p =
3. n = 25,T = 2.6, two-tailed:p =
4. n = 15, T = -1.9, one-tailed (lower):p =
