Question 15 7 pts Two plots of roses are the same except for the fertilizer used. A random sample is drawn from both plots and the heights of the roses measured. Assume the populations that the samples are drawn from are normal and that the population variances are different/not equal Group 1 used fertilizer A and Group 2 used Fertilizer B. The company selling Fertilizer A claims that it helps flowers to grow taller. The following data is gathered. Group 1 = 26.8 cm Group 2 25.2 cm $13.7 82 = 4.6 12 31 2 = 32 Preform a significance test with a-0.05 to determine if Fertilizer A causes the roses to grow taller by following the steps listed: a) State your Hypotheses mathematically (not in words) b) Confirm the Assumptions to test difference of the population means; c) Find the Test Statistic (Round to 3 decimal places): d) Critical Value(s)/Region(s); e) Conclude your test: Reject H, or Fail to Reject H, ? f) Interpret your conclusion in the context of the claim:
