Solution

A test of H₀: u=0 based on n=16 calculates t_stat = 2.44.

A) Determine the degrees of freedom for the test statistic.

degrees of freedom = 16-1=15

B) Provide the t-values from the Table C that bracket the t_stat.

0.05 level t value =2.131

0.01 level t value =2.947

C) What is the approximate one-sided P-value for the problem?

P= 0.0138

D) What is the two-sided P-Value

P=0.0276
