Cardiff Maths Support tutorial video on Two Sample t-tests.

Not that it matters for a sample size bigger than 30 but you actually need to look for t34. not 35. 
you're dealing with 2 samples. therefor you need to reduce 2 degrees of freedom.
n1 + n2 - 2.

Since you are dealing with two different means and two different samples, shouldn't your degrees of freedom be n-2?

My teacher ask us to find out critical value. Can u please help on this?

[GooseJaffa]

Dont think it should be 12 divided by the square root of 1 over n, should be 12 divided by sq root of n? Maybe not

[allendran]

should be standard deviation over square root of n on the bottom.
