An advocacy group claims that Blacks/African-Americans are over-represented in the incarcerated population. In other words, they are claiming that there is a higher percentage of Blacks/African-Americans in the incarcerated population than in the general US population. A random sample of 150 US residents is sampled and 26 identify as Black/African-American. In another random sample of 40 US incarcerated individuals, 14 identify as Black/AfricanAmerican. Is there enough evidence to support the group’s claim at the 1% level of significance?

A. State the claim mathematically. Is the claim the null or alternative hypothesis?

B. State your hypotheses.

C. Determine the test of significance (t-test or z-test) and justify your choice.

D. State the standardized test statistic.

E. State the p-value.

F. State the correct decision of the test.

G. Interpret the decision in the context of the claim.

I really need help as soon as possible with this question, thank you!

         A group of researchers wants to determine if Caucasians and African-Americans are equally likely to inherit cystic fibrosis (CF). They collect data on cystic fibrosis (yes/no) and calculate frequencies for each group. They collected data from 820 people overall. They observed the following frequencies: White-YesCF (80), White-NoCF (430), Black-YesCF (16), Black-NoCF (294). Use a two-variable chi-square analysis (where α = .01) to determine if there are significant differences in cystic fibrosis by race.         7.      Identify the null hypothesis        ...

In an African population the ABO blood group antigens alleles at the I locus were found in the following frequencies: IA = 0.12 IB = 0.56 IO = 0.32 What are the expected genotype frequencies in the population? what are the expected frequencies of the A, B, AB, and O blood types? (remember IA points) and IB are codominant alleles and IO is a null allele).
