t-test for independent means

A group of researchers hypothesized that under a quiet condition, students would perform better compared students under a noisy condition. To test this idea, they randomly assigned 9 participants into one of the two conditions (quiet vs. noisy) and asked them to take a math test. Here are the data from the study 1. Conduct a hypothesis testing using the 5 steps with a-05 and one-tailed test. Data QUIET CONDITION Participants Score RX 22 BL 20 JC 23 DM 21 FM 19 NOISY CONDITION Participants Score KA 17 BI 15 OF 16 BK 20 O Restate question as a research hypothesis and a null hypothesis about the populations. Population 1: Population 2 Research hypothesis: Null hypothesis: @ Determine the characteristics of the comparison distribution. Determine the cutoff sample score on the comparison distribution at which the null hypothesis should be rejected. Determine your sample's score on the comparison distribution 6 Decide whether to reject the null hypothesis. Report the results from the t-test with a written conclusion of this study
