Calculating the P-value in a t test for a mean

AP.STATS: VAR‑7 (EU), VAR‑7.E (LO), VAR‑7.E.1 (EK)
You might need: t table

Problem

Amelie was testing H, start subscript, 0, end subscript, colon, mu, equals, 15 versus H, start subscript, start text, a, end text, end subscript, colon, mu, is less than, 15 with a sample of 10 observations. Her test statistic was t, equals, minus, 2, point, 77. Assume that the conditions for inference were met.
What is the approximate P-value for Amelie's test?
