1.n=30, H0: mean=10, HA: mean<10, level of significance=0.01

Suppose the t statistic were calculated to be t = -3.141. Applying the t distribution approximation, what is the greatest lower bound for the corresponding p-value that is implied by the above critical value table? What is the least upper bound for the p-value?

Now using a normal approximation to the null distribution of the t statistic, what is the greatest lower bound for the p-value that is implied by the above critical value table? what is the least upper bound for the p-value?


2.n=21, H0: mean=100, HA: mean not equal 100, level of significance=0.05

Suppose the t statistic were calculated to be t = -0.242. Applying the t distribution approximation, what is the greatest lower bound for the corresponding p-value that is implied by the above critical value table? What is the least upper bound for the p-value?

Now using a normal approximation to the null distribution of the t statistic, what is the greatest lower bound for the p-value that is implied by the above critical value table? What is the least upper bound for the p-value?
