◦

False



Question 2

To test the effects of acid rain on the growth of white pine trees, a conservationist measures the diameter (in centimeters) of 200 white pines in the Allegheny National Forest in northwest Pennsylvania. The average diameter of the sampled trees is 23.42 cm. Does the sample provide sufficient evidence to conclude that the current mean diameter of the white pines is less than that recorded 50 years ago (μ= 24.8) if the standard deviation is 6 cm? Calculate thep-value and make an appropriate decision. (Useα= 0.05).

◦

p-value = 0.9994; fail to rejectH0


◦

p-value = 0.0006; rejectH0


◦

p-value = 0.0006; fail to rejectH0


◦

p-value = 0.9994; rejectH0
