◦

True


◦

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

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
