With regard to Lasperye's and Paasche's price index number, it ismaintained that "if the prices of all the goods change in the same ratio,the two indices will be equal for then the weighting system is irreleventor if the quantities of the goods change in the same ratio, they will beequal, for then the two weighting systems are the same relatively."

A manufacturing company has three processing lines. Each processing line combines various raw materials to produce the same output, Y. One of the processing lines can combine units of input (X) to produce units of output (Y) such that there is a linear relationship between X and Y. The Chief Executive Officer wants the output model to be estimated for this processing line. Given the values of X and Y (in thousands of units) in the table below, and as the Director of Data Management, you are to: x 5 7 2 8 4 8 12 6 14 8 Determine the extent to which output changes as the input change and interpret your result. Find the intercept of the output model and interpret it. Write down the equation of the line of best fit for output. Determine the value of the extent of relationship between input (X) and output (Y), and interpret your result.

The average sodium content of single serving of Special K is not significantly equal to 220 mg.
Based on Angel et al. (2003). A fertilizer companyis trying to determine the cheapest fertilizer mix thatprovides desired amounts of nutrients. The mix ismade by combining the following fertilizers: SSA,SPO, GUR, TSP, KCI, FERT, and SPF. The mix cannot contain both GUR and TSP. The percentage ofpotassium (K), sulfur (S), calcium (Ca), sodium (Na)and phosphorus (P) in each fertilizer is listed in the fileP06_88.xlsx. For example, a pound of SSA is 16% Kand 26% Na. The mix must contain at least 600 poundsof K, 550 pounds of S, 750 pounds of Ca, 900 poundsof Na, and 750 pounds of P. The mix cannot containboth GUR and TSP, because if both are present in themix, the affect of other fertilizers is nullified. The costper pound (in cents) of each fertilizer is listed in thesame file. Develop a linear integer model to find theminimum-cost fertilizer mixture that meets the statedchemical requirements.
The following table gives the cost of living index for 1998 with 1986 as base for different commodity groups: Food, Clothing, Fuel and Light, Rent and Miscellaneous as 440, 500, 350, 400 and 250 respectively with their weights in order in the ratio 15: 1:2:3:4. Obtain, the overall cost of living index number, suppose a person was earning $ 4,000 in 1986. What should be his salary in 1998 to maintain the standard of living as in 1986?

1. Whenever we look at the relationship between two variables (regardless of the level of measurement of those variables), we are interested in two aspects of that relationship. What are those two "aspects" and why is each important? (You can discuss more than two if you feel it necessary).
When looking at the data for graduate school admissions between men and women, it is shown that about 45% of men are admitted but only 38% of women. However, when the data is broken down by school it turns out that, within each school, the women are admitted at higher rates than the men. This could happen because I. The women apply in higher numbers to schools with lower acceptance rates. II. The women apply in higher numbers to schools with higher acceptance rates III. The men apply in higher numbers to schools with lower acceptance rates IV. The men apply in higher numbers to schools with higher acceptance rates

The TSS means that 437 variations in the dependent variables are explained by regressors B. 40% of the regression power is explained by the error term. C. 33.4% variations in the dependent variable are explained by the independent variable(s) D. The independent variables in the model are significant. 146 3. The regression model includes a random error or disturbance term for a variety of reasons. Which of the following is not one of them? A. Measurement errors in the observed variables. B. To capture unobserved omitted relevant influences on y. VSS=RSt° C. A linear functional form may only be an approximation. D. To capture unobserved…
