**Question**: Which of the below Z scores is the appropriate $ z^* $ when calculating a 98% confidence interval?**Options**:(a) $ Z = 2.05 $(b) $ Z = 1.96 $(c) $ Z = 2.33 $(d) $ Z = -2.33 $(e) $ Z = -1.65 $When calculating a 98% confidence interval, the correct $ z^* $ value represents the Z score that encompasses the central 98% of the standard normal distribution, leaving 1% in each tail. Therefore, the correct answer is:(c) $ Z = 2.33 $This Z score corresponds to the positive critical value needed for a 98% confidence interval. A negative value (like in options d and e) is incorrect in this context because confidence intervals conventionally use the positive Z score.

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.

The website of the large coporation CorpPlus claims that 97% of the population of all employees say the corporation is a great place to work. You work for a competitor and think that this percentage is not a true indicator of CorpPlus's employee satisfaction. To test the daim from the website, you will survey a random sample of 75 employees from CorpPlus, and ask them whether they think the corporation is a great place to work. Follow the steps below to construct a 99% confidence interval for the population proportion of all employees who say the corporation is a great place to work.
