Question

When the background music tempo was slow, the mean amount of bar purchases for a sample of 17 restaurant patrons was $30.46 with a standard deviation of $15.40. When the background music tempo was fast, the mean amount of bar purchases for a sample of 15 patrons in the same restaurant was $21.03 with a standard deviation of $9.50. Assuming equal variances, at α = 0.05, is the true mean higher when the music is slow? 1. appropriate hypotheses: H0: μ1 – μ2 ≤ 0 vs. H1: μ1 – μ2 > 0. Reject H0 if tcalc > 1.697 2. Calculate the tcalc. (Round your answer to 3 decimal places.) ???? 3. Based on the t-value determined, choose the correct decision. Reject the null hypothesis OR Fail to reject the null hypothesis 4. Calculate the p-value using Excel. (Round your answer to 4 decimal places.) ?????
