Rоses аre very pоpulаr, but оnce they hаve been cut and placed in a vase filled with water, they only last a few days before they begin to wilt. A botanist is attempting to create hybrid roses that would have a longer vase-life before wilting. They conduct an experiment comparing the vase-life of 6 of the new hybrid roses and 12 ordinary roses. Using the information in the table below, conduct a hypothesis test at the .10 level of significance to determine whether the results support the belief that the new hybrid roses have a longer vase-life than ordinary roses. Ordinary Roses(Sample 1) Hybrid Roses(Sample 2) Sample Size 12 6 Sample Mean 7.2 days 8.4 days Sample Standard Deviation 2.2 days 1.8 days (A) Which pair of hypothesis statements below would be appropriate for the test?
