A blood analysis was performed on 3,000 blood samples from newborn babies of Caucasian descent in the state of Michigan, USA. The results showed that 163 of those sampled carried two mutations in the HFE gene. d. If the researcher wanted to halve (x ½) the margin of error in the confidence interval found, what sample size would be required for the same data and level of confidence? No Full re-calculation is required for this e. A nationally accepted level of HFE gene prevalence nationally in non-Caucasians in the Michigan State is 3%. Explain if there is evidence that the Caucasians in Michigan have a different rate or proportion of the mutation to non-Caucasians. NOTE that it is NOT necessary to use a separate test of significance
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
hi last parts of a question I posted weren't answered, and I was asked to just post those parts again.
Hereditary hemochromatosis (HH) is a recessively inherited genetic disorder resulting from mutations in the HFE gene. There are several possible mutations of different degrees of importance but the disease expresses itself only when at least 2 arepresent in any one individual.
