you are analyzing the variables that explain the returns on the stock of the Boeing Com- pany. Because overall market returns are likely to explain a part of the returns on Boeing, you decide to include the returns on a value-weighted index of all the companies listed on the nySe, aMeX, and naSdaQ as an independent variable. Further, because Boeing is a large company, you also decide to include the returns on the S&P 500 index, which is a value-weighted index of the larger market-capitalization companies. Finally, you decide to include the changes in the uS dollar’s value. to conduct your test, you have collected the following data for the period 1990–2002. Rt = monthly return on the stock of Boeing in month t RALLt = monthly return on a value-weighted index of all the companies listed on the nySe, aMeX, and naSdaQ in month t RSPt = monthly return on the S&P 500 index in month t ΔXt = change in month t in the log of a trade-weighted index of the foreign exchange value of the uS…
A school district started using a new criteria for selecting which students entered their "accelerated" math track, starting in 6th grade. The study found that under the new criteria about 75% of the students in the district were eligible for accelerated math in 6th grade, but that from one year to the next only about 2/3 of the students stayed in the accelerated track. a) Assuming that everyone who is eligible enrolls the first year, make a TABLE that shows the percent of the students in the district that would be expected to be enrolled in the accelerated track each year from 6th grade until 10th grade. Please show the work you used to fill in your table. b) Considering that from one year to the next about 2/3 of the students stay in the accelerated track, is there a grade level in which you'd expect about 1/10 as many students in the accelerated track as there were in 6th grade? Does the number of students in the accelerated track in 6th grade affect your answer? Please show your…
For the past years, 20% of the babies were delivered through cesarean section. The research group randomly inspects the medical records of 144 births and finds that 25 of births were by cesarean section. Can the researcher group conclude that the percent of births by cesarean section has decreased at 5% level of significance?
Suppose two households earn $40,000 and $56,000 respectively. What is the expected percent difference in wages between the children, grandchildren, and great-grandchildren of the two households if the intergenerational correlation of earnings is 0.2, 0.4, or 0.6?
Suppose that in the previous semester, the percentages of students in the five sections of ECO 204 were 20%, 21%, 19%, 15% and 25%. However, in the current semester, among a sample of 200 students, the student distribution among five sections is 51, 49, 30, 20 and 50. Can we conclude that there has been a statistically significant change in the student proportions?
Jane White has recorded the following sales figures for last year for herbusiness: January, $35,645; February, $35,456; March, $31,270; April,$32,129; May, $34,456; June, $35,256; July, $36,218; August, $35,456;September, $34,250; October, $32,156; November, $30,125; December,$32,275. She wants to select from one of three models: a 3-month movingaverage, a weighted moving average (she believes that the weightsshould be 0.2, 0.3, and 0.5), and an exponential smoothing average inwhich she uses an α of 0.2 and an assumed forecast for January of Year 1of $35,000.a. Construct a table that shows each of these forecasts for the current year andprovide the forecast for January of Year 2.b. Using the available data and your forecasts, which model do you suggest thatJane use for her business?
Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. At a financial institution, a fraud detection system identifies suspicious transactions and sends them to a specialist for review. The specialist reviews the transaction, the customer profile, and past history. If there is sufficient evidence of fraud, the transaction is blocked. Based on past history, the specialist blocks 40 percent of the suspicious transactions. Assume a suspicious transaction is independent of other suspicious transactions. (a) Suppose the specialist will review 136 suspicious transactions in one day. What is the expected number of blocked transactions by the specialist? Show your work. (b) Suppose the specialist wants to know the number of suspicious transactions that will need to be reviewed until reaching the first transaction that will be…
Most engaged couples expect or at least hope that they will have high levels of marital satisfaction. However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital satisfaction. Suppose a clinical psychologist sets out to look at the role of economic hardship in relationship longevity. She decides to measure marital satisfaction in a group of couples living above the poverty level and a group of couples living below the poverty level. She chooses the Marital Satisfaction Inventory, because it refers to “partner” and “relationship” rather than “spouse” and “marriage,” which makes it useful for research with both traditional and nontraditional couples. Higher scores on the Marital Satisfaction Inventory indicate greater satisfaction. There is one score per couple. Assume that these scores are normally distributed and that the variances of the scores are the same among couples living above the poverty level as among couples…
