An independent-samples t-test provides the followingdata: t-obt is 2.66, t-crit is 2.086What is the correct statistical conclusion here?O We fail to reject the null hypothesis and conclude that there isa significant difference between the groups' meansWe reject the null hypothesis and conclude that there is nosignificant difference between the groups' meansO We reject the null hypothesis and conclude that there is asignificant difference between the groups' meansO We fail to reject the null hypothesis and conclude that there isno significant difference between the groups' means

Hypothesis testingGiven observed t=2.66 and t critical=2.086 Since t observed is greater than critical value, we reject the null hypothesis (of no difference) and conclude that there is significant difference between the two groups means. (Option 3)
