Homework SourseThe pvalue of a twosides test is equal to PrT
\"The p-value of a two-sides test is equal to Pr(T<=[t]), where T has the appropriate t-distribution and t is the value that was actually obtained.\" True or false? If false explain. How about \"The p-value of a two-sided test is equal to 2•Pr(T<=-[t]), where T has the appropriate t-distribution and t is the value that was actually obtained.\" True or false? If false explain. And \"The p-value of a one-sides test is equal to Pr(T>=[t]), where T has the appropriate t-distribution and t is the value that was actually obtained.\" True or false? If false explain

Solution
1. False. The p value for 2 sided t test is 2*P(T<=t)
2. True.
3. False. The p value for one sided t test is P(T<=t).
