What is the PValue if T0 277 and N63 Round to three decimal

What is the P-Value if T0= -2.77 and N=63? (Round to three decimal places)

Solution

Note that

df = n - 1 = 63 - 1 = 62

Using a table, if it is a one tailed test,

P(one tailed) = 0.003693351

If it is two tailed,

P(two tailed) = 0.007386703 [ANSWER, DEPENDS ON THE NUMBER OF TAILS]
