Recall the weak form of the efficient markets hypothesis. It

Question Recall the weak form of the efficient markets hypothesis. It states that there is no useful information in past pricesor returns that would allow us to forecast future returns. You will test this hypothesis with a time series of daily returns for Apple.Suppose you could forecast future stock prices by examining patterns in past prices or returns. This would be a great way to make money, and there is a field of study, technical analysis, where practitioners try to identify recurring patterns in stock prices and returns. However, there is a considerable body of evidence suggesting there is no useful memory in past prices. Let’s do a quick experiment. The spreadsheet attached to this assignment contains two years of daily stock returns for Apple. The experiment is simple. Is today’s return explained by the returns generated over each of the previous five trading days?The regression approach can be modeled like this:Rt= a b1(Rt-1) b2(Rt-2) b3(Rt-3) b4(Rt-4) b5(Rt-5) eThe spreadsheet contains 502 daily returns. These are your Rt, or dependent variables. You will need to create five additional columns with the lagged returns. The lagged returns are just those occurring one, two, three, four, and five days prior to a particular value of Rt. Note that this means you must discard the first five observations. It’s not until the fifth day of your sample that you can compute a complete set of independent variables.1.What are the null and alternative hypotheses associated with this test?2.Run the regression described above. Discuss your results. Do they support the weak form of the efficient markets hypothesis? Why or whynot?3.Attach a copy of the Excel output for your regression analysis.Download and save theProblem Set 3 (EXCEL)file to your computer.Part2:Recall the analysis of our sample of small cap growth oriented mutual funds in Lesson 2. The data behind this analysis is linked to a slide within the lesson. In the analysis presented in Lesson 2, we ran two regressions. The first employed logtna (thelog of total net assets under management, column E) and a number of control variables to explain returns on our sample of funds. The second regression added [logtna -avg.logtna]2, denoted on the spreadsheet as 22FINA6206:FinanceSeminarsize_sq (column F).1.Rerun the first regression using the raw (unlogged) values of total net assets (column D on the spreadsheet instead of column E). Use the control variables in columns G through J as well. (Note: You may want to rearrange the columns before running the new regression.)2.Before rerunning the second regression, recreate the values for the quadratic term, size_sq (column F) using raw (unlogged) values of total net assets. In other words, create a variable: [tna -avg.tna]2.Now rerun the second regression.3.Calculate VIFs for each independent variable.Is multicollinearity a problem with this regression?4.Discuss your results for both of the new regressions focusing on the expected signs and significance of the independent variables. Also discuss any differences between these results and the original regressions that used the logged values of total net assets.Submit your answers using the drop box in the Assignments area of the course.

The payment is based on the IPPS and so it is driven by three primary components: DRG weight, wage index (cost of living), and outlier payments. We can investigate to see if the DRG mix is the cause of the payment differences by creating a variable that estimates the proportion of cases with either a CC (MS-DRG 065) or MCC (MS-DRG 064). The following table was created based on the sample data set. 064 – Intracranial 065 – Intracranial 066 – Intracranial Hemorrhage or Hemorrhage or Hemorrhage or Cerebral Infarction Cerebral Infarction Cerebral Infarction w/MCC w/CC w/o CC or MCC Toledo 204 315 199 Youngstown 53 191 145 The hypothesis test may be formulated as: 1.

The town’s tax assessor wants to be 90% confident that

Question The town’s tax assessor wants to be 90% confident that the average value of one-acre lots in her town is $60,000. She takes a sample of 25 randomly selected lots, having a standard deviation of $5,000 and a mean of $57,000. Based on this information, which of the following statements would be correct?         Formula Choices:  x-bar ± z (σ÷n)  x-bar ±  t (s÷n)µ ± z (s÷n) µ ±  t (s÷n)   To estimate the lot values the tax assessor should use a z-value = 1.645To estimate the lot values the tax assessor should use a z-value = 1.28To estimate the lot values the tax assessor should use a t-value = 1.711To estimate the lot values the tax assessor should use a t-value = 1.316 Flag this QuestionQuestion 242 ptsUsing the information provided in the previous question, if the tax assessor calculates a confidence interval of $58,289 – $61,711 for the average lot value, referencing the data results of her sample she should:Reject H1 because Mu (the population mean) is less than the critical value.Accept H0 because Mu (the population mean) is greater than the critical value.Reject H0 because x-bar (the sample mean) is less than the critical value.Accept H0 because x-bar (the sample mean) is less than the critical value. Flag this QuestionQuestion 252 ptsIn reference to the tax assessor’s decision in the previous question:there is a 10% probability that she is making a Type I error.there is a 10% probability that she has made no error.there is a 5% probability that she is making both Type I and Type II errors.there is a 10% probability that she is making a Type II error. Flag this QuestionQuestion 262 ptsTo reduce the probability of making a Type I or a Type II error, the tax assessor should: increase the number of lots included in the sample.decrease the confidence level.increase the standard deviation of lot values included in the sample.decrease the number of lots included in the sample.
