I am new to statistics to please bear with me.
I am using a t test to compare a sample mean to a population mean (it's a question in a book). The t test gives a vaslue of 2.536. This gives a two tailed probability of
0.02 <p <0.05
and a one tailed probability of
0.1 < p< 0.025
The two tailed probability is double the one tailed probability. This doesnt make sense to me. Shouldn't it be the other way around.
Please can you clarify for me
