using the following information, determine if the differences between the means are significant medical terminolgy class. Group A = number of word elements remembered by students using flash cards, group B= number of word elements remembered by students not using flash cards. group A, mean = 75; sd = 2.0 ; n = 10. Group B mean = 50, sd = 3.5, n = 10 The null hypothesis: There is no difference between the groups. H0: µ1 - µ2 = 0 (the difference between the means is zero) (t = 2.50, df= 18,p < 0.05

what are the answer choices
No choices given. I am at a complete loss at where to begin with this problem.
t with 18 df at .05 = 2.101
What does that tell you?

P <0.05,
It is statistically significant at the .05 level.
