Plant breeders are attempting to develop a new strain of dogwood tree that is resistant to air pollution. In one study of their progress, a random sample of n = 45 seedlings of the new strain was selected, and the seedlings planted at random locations in a particular industrial region. Results indicate that 27 of those seedlings died within three years. Historical records show that 70% of an existing strain of dogwood tree planted in that region died within three years.

Choose the correct alternative hypothesis for the test of whether the new strain of dogwood tree has a lower death rate within three years than the existing strain when planted in the industrial region.
