Problem 1. (50pts)

From microeconomic theory it is known that the demand for a commodity generally depends on the income of the consumer, the real price of the commodity, and the real price of complementary or competing products. Chicken.xls includes the per capita consumption of chicken (in pounds) in the United States for 1960-1982 along with disposable income per capita (in dollars) and the retail prices for chicken, pork, and beef (in cents).

A research firm specializing in agricultural economics has recruited you. Your first assignment is to assist one of the principals in the firm with a study for a chicken franchise on the price elasticities for various meat products.

(1.1) Plot chicken consumption vs. chicken price and calculate the correlation coefficient between these two variables. Describe the relationship. Does it make economic sense? Offer your explanation briefly. (10pts.) As price increases consumption increases but this is correct as income increases as well. Eventually, consumption levels off, as the increasing wealth means people spend their money on other meats instead of chicken. The correlation coefficient =.794, which means this does have a positive linear correlation.

(1.2) Run a linear regression:
Chicken price vs. consumption Chicken w/beef+pork+ beef

Chicken consumption over time increases

Chicken consumption=b0+b1*Income+b2*chicken price+b3*pork price+b4*beef price
What’s the estimated regression equation? (5pts.)

(1.3) Identify significant and insignificant variables. Does the chicken consumption statistically depend on the beef and pork prices and the income? Give the statistical reason briefly (p-value). (5pts.)

Significant=chicken

    P-value is 0.000; this means that there is extremely strong evidence of a relationship between the price of a used Mustang and the mileage of the car. We used the critical value F.05 based on 1 numerator and 33 denominator degrees of freedom. From the F table we find that at 95% critical value for Price vs. Miles = 4.139 while F = 42.34. Since the F (model) for Price vs. Miles = 42.34 which is greater than F.05 =4.139 we can reject the null hypothesis in favor of the alternative hypothesis at level of significance 0.05. The test tells us that if we reject the null hypothesis then we have evidence of a relationship between the prices vs. Miles of the used Mustangs. The Small P-value for the F test is evidence of a significant relationship between the…

    As we has discussed, elastic demands are placed upon items that are commodities rather than needs. The change of eggs prices are forced due to the demand. During the summer months, egg supply is higher and lower during the winter months. Beef prices change when with customer preference such as competition, safety concern, income, etc. Demand shifts do not cause the price changes in the norm. Somethimes, the government will intervene to affect prices of these items as well. Supply and deman have no affect upon equilibrium price by definition. The equilibrium price is when neither of these items affects the sale. For example, during Easter, consumers will buy eggs to color at home for their kids and host Easter egg hunts. Regardless of the supply or price, the demand will increase. Beef has more of a buying response because it is very convenient for consumption; and can be used to make various dishes. There are some beliefs that beef has more vitamin content as well.…

    In section 1, we will present a Causal Relationship Scheme (CRS) that will be used as the framework of our research establishing the different relationships among our selected variables. Section 2 of the report contains the results of our univariate analyses. The distribution, mean and amount of variation of the data will be discussed. The subsequent section then introduces our findings from the bivariate analyses, investigating the presence, nature and strength of the relations between the pairs of variables described in the CRS. The fourth section presents the results of three multivariate analyses consisting first of a 2-factor ANOVA analysis that involves the response variable price and two other factors belonging to the CRS of the report. Secondly, we will formulate a regression model based…
