You run a one-sided test where Ho: u=20, and H1:u>20. Your t-statistic is t =1.7

Question

You run a one-sided test where Ho: u=20, and H1:u>20. Your t-statistic is t =1.75, and your software reposts that the p-value for a two-sides test is 0.08. What should your p-value be? How about when your H1 becomes u<20? How about when your t =-1.75? You run a one-sided test where Ho: u=20, and H1:u>20. Your t-statistic is t =1.75, and your software reposts that the p-value for a two-sides test is 0.08. What should your p-value be? How about when your H1 becomes u<20? How about when your t =-1.75?

Explanation / Answer

When Ho: u=20, and H1:u>20, t-statistic is t =1.75
should p-value be,
P-Value :Right Tail - Ha : ( P > 1.75 ) = 0.05183

When H1 becomes u<20
P-Value :Left Tail -Ha : ( P < 1.75 ) = 0.94817

When your t =-1.75, H1: u<20
P-Value :Left Tail -Ha : ( P < -1.75 ) = 0.05183
