Question

In one study of their progress, a random sample of n = 60 seedlings of the new strain was selected, and the seedlings planted at random locations in a particular industrial region. Results indicate that 25 of those seedlings died within three years. Historical records show that 80% of an existing strain of dogwood tree planted in that region died within three years.

Compute the test statistic for the hypothesis 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.

What is the p-value for this test? (Round your p-value to 2 decimal places).
