S(x)=2.66 S(y)= 2.34
Test to see whether the difference between mean male and female is 5.5 inches.
I got the test statistic which was 3.57, and the pooled estimate variance to be 2.57
The problem is i cant get the p value, i dont understand where i am meant to look in the tables.
In my book it says the forumula to get the P-Value is: P=2*P(T>|t|) ,where t is observed value.
Any help please
