Question

Suppose that your hypotheses are H0:μ=25 and Ha:μ<25. In the context of these hypotheses, which of the following t-test statistics would provide the strongest evidence against the null hypothesis and for the alternative hypothesis?

Select one:

t = -1

t = 0

t = 3

t = -1.80

t = 25

Answer 1

This is left tailed test.

So, test provide strongest evidence against null hypothesis if test statistics has maximum negative value

That is for t = -1.80
