.1) Determine the values necessary to calculate the t statistic.
Type in the Sample Mean, Population Mean, and Standard Error. Please label which number is which.
x:- base frustration levels before playing game
y:- base frustration levels after playing game
d = difference in base frustration levels after & before playing the game.
d = y - x
x | y | d | d^2 |
