(b) Answer part (a) if you use the preliminary estimate that about 8 out of 90 people have blood type B (Reference: Manual of Laboratory and Diagnostic Tests by F. Fischbach).

Color blindness, or dyschromatopsia, is a form of genetic deficiency in color perception. The condition is much more prevalent among males than females, pointing to a genetic connection with the X chromosome. The frequency of dyschromatopsia in the Caucasian American male population is about 8%. However, it is thought that this proportion might be smaller among males of other ethnicities. We want to estimate the proportion of Asian American males who are color-blind. How large a sample size do we need in order to obtain a 95% confidence interval with a margin of error no greater than 4%, or 0.04?

Incidence rate in the last influenza epidermic was found to be 50 per thousand (5) of the population exposed. What should be the size of a sample to find incidence rate in the current epidemic if allowable error is 0.005 and 0.01?
Every 5 years a city conducts a survey of residents to collect data on various political, economic, an health indicators. With a new survey coming this year the mayor is especially concerned with jobs and the economy. In the last survey only 41% of people in the city said they felt very secure in their job. The mayor wants to be able to estimate that proportion for this year to within a margin of error of +/- 2%. How large of a sample will be needed.

- Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Fingerprint analysis and blood grouping are features that do not change through the lifetime of an individual. Fingerprint features appear early in the development of a fetus, and blood types are determined by genetics. Therefore, each is considered an effective tool for identification of individuals. These characteristics are also of interest in the discipline of biological anthropology—a scientific discipline concerned with the biological and behavioral aspects of human beings. The relationship between these characteristics was the subject of a study conducted by biological anthropologists with a simple random sample of male students from a certain region with a large student population. Fingerprint patterns are generally classified as loops, whorls, and arches.

PepsiCo, the owner of Frito-Lay, decide to run an internal investigation of their Doritos chip production. They sample around 500 bags of chips to discover that they found an average of 1.59 ounces with a standard deviation of .12 ounces. Conduct a hypothesis test with an alpha-level of .05.
