A restaurant chain is measuring the levels of arsenic in chicken from its suppliers. It takes money and time to test for arsenic, so samples are often small. Suppose n = 6 chickens from one supplier are tested, and the levels of arsenic (in ppb) are 64, 71, 85, 94, 98, 130 1. Use Statkey to construct a 90% confidence interval for the mean level of arsenic in all chickens from this supplier. 2. Use the standard error method (i.e., formula method) to give the 95% confidence interval for the mean level of arsenic in chickens from this supplier.
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.
