A fictitious city of 1,000,000 residents has three neighborhoods: A, B, and C. You are interested in understanding whether a person’s residential location is related to their occupation. You take a random sample of 400 residents and classify their occupation as white collar (service), blue collar (manufacturing), or green collar (environment). The data are tabulated as follows. Conduct a Chi Sq. test, State your null and alternative hypothesis. Provide your test statistic, critical value (at 0.05 significance), and decision (reject or fail to reject).

	A	B	C	Total
White Collar	76	51	88	215
Blue Collar	21	38	28	87
Green Collar	19	18	61	98
Total	116	107	177	400

Expert Solution

Hypothesis,

H0 : person’s residential location is not related to their occupation.

H1 : person’s residential location is related to their occupation.

Conclusion:

As null hypothesis is rejected at 5% los, we conclude that the person’s residential location is related to their occupation.

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...

5. You are looking for a home in three neighborhoods. In one neighborhood, the mean price is much smaller than the median price. In a second neighborhood the mean and median price are the same. In the third neighborhood, the mean price is larger than the median price. What does this information tell you about homes in the three neighborhoods? Would you be more inclined to buy a home in one neighborhood than the two others? Explain your reasoning. Exercise...
