Question

You conduct a t test for independent means and reject the null hypothesis. This means that:
a)the mean of one sample is statiscally the same as the eman of the other sample, so they probably come from the populations with equal means
b)the mean of one sample is so far fromt he mean of the other sample that you decide the samples must come from poulations with different means
c)the variance of one sample is so much larger than the variance of the other smaple that you decide that the variances of the parent populations must not have been the same
d) the samples were from populations that were actually dependent rather than independent

Explanation / Answer

b) is the correct answer the null hypothesis is that the means are equal, so by rejecting the null hypothesis we're saying that the means are not equal
