Male Female

m=41 n=17

x(bar) =69.2 y(bar)= 66.7

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
