After concluding an experiment, the researcher analyzed the data using a t-test.  The researcher obtained a value of t(23) = -4.58.  The researcher then determined that the critical value for a two-tail test with df=23 and α = .05 is 2.069.  What conclusion should the researcher make?     The researcher should reject the null hypothesis and say there is a significant difference.     The researcher should reject the null hypothesis and say there is not a significant difference.     The researcher should fail to reject the null hypothesis and say there is a significant difference.     The researcher should fail to reject the null hypothesis and say there is not a significant difference.
