Calculate the test-statistic, t with the following information. n1=40, ¯x1=2.93, s1=0.51, n2=30, ¯x2=2.88, s2=0.66

Question

Calculate the test-statistic, t with the following information.

n1=40,   ¯x1=2.93,   s1=0.51,  n2=30,  ¯x2=2.88,  s2=0.66

Rounded to 2 decimal places.

Answer 1

t = (xbar1 - xbar2/sqrt(s1^2/n1 + s2^2/n2)

plug the values you are given for the terms in the right side of the equation to compute t.
