State the distribution to use for the test. (Round your answers to four decimal places.) O Part (e) What is the test statistic? (If using the z distribution round your answers to two decimal places, and if using the t distribution round your answers to three decimal places.) O Part (f) What is the p-value? (Round your answer to four decimal places.) Explain what the p-value means for this problem. O If H, is true, then there is a chance equal to the p-value that the average age of people when they first begin to smoke is 18.2 years or less. O If Ho is true, then there is a chance equal to the p-value that the average age of people when they first begin to smoke is not 18.2 years or less. O If Ho is false, then there is a chance equal to the p-value that the average age of people when they first begin to smoke is not 18.2 years or less. O If Ho is false, then there is a chance equal to the p-value that the average age of people when they first begin to smoke is 18.2 years or less.

Ratios

A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.

Trigonometric Ratios

Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
