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.
