Solution Steps

Step 1: Understanding Ozone-Depleting Substances

Ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs) are chemicals that contribute to the depletion of the ozone layer in the Earth's stratosphere. These substances are stable and can persist in the atmosphere for a long time.

Step 2: Analyzing the Longevity of CFCs

CFCs are known for their long atmospheric lifetimes, often lasting for decades. This stability allows them to reach the stratosphere, where they release chlorine atoms that catalyze the breakdown of ozone molecules.

Step 3: Evaluating the Statement

Given the long atmospheric lifetimes of CFCs, the statement "Ozone-depleting substances like CFCs go away quickly" is false. CFCs do not dissipate quickly; they remain in the atmosphere for extended periods, contributing to ozone layer depletion over time.

Explain the difference between the z-test for μ using rejection region(s) and the z-test for μ using a P-value. Choose the correct answer below. A. The z-test using rejection region(s) is used when the population is not normal. The z-test using a P-value is used when the population is normal. B. In the z-test using rejection region(s), the test statistic is compared with the level of significance α. The z-test using a P-value compares the P-value with the critical values. C. In the z-test using rejection region(s), the test statistic is compared with critical values. The z-test using a P-value compares the P-value with the level of significance α. D. The z-test using rejection region(s) is used when the population is normal. The z-test using a P-value is used when the population is not normal.
