Using technology how do I find the Pvalue for a twotailed te

Using technology how do I find the P-value for a two-tailed test with n=21 and test statistic t+1.557. Showing p-value = 0.1352?

Solution

n =21

As sample size is 21, calculate degrees of freedom = n-1 = 21-1 =20

Test statistic = 1.557
