Which of the following is correct for  for a two-tailed test? tcrit = + tcrit = ± tcrit = ˗

Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is μd = 0. Compute the value of the t test statistic. Round intermediate calculations to four decimal places as needed and final answers to three decimal places as needed.A farmer has decided to use a new additive to grow his crops. He divided his farm into 10 plots and kept records of the corn yield (in bushels) before and after using the additive. The results are shown below. You wish to test the following hypothesis at the 10 percent level of significance. H0: μd = 0 against H1: μd ≠ 0.What is the value of the appropriate test statistic?
