Question First, note that the proper word for your RQ and hypotheses, etc. is “association” not “connotation”. You started off OK describing the initial steps followed and included the SPSS codebook and output. However, you cannot conduct a chi-square analysis on an interval/scale variable.  As per my feedback from Week 7, you need to recode AIDS to make it a nominal variable (Yes/No), whereby any case with a CD4 cell count of <200 = yes (AIDS) and those with CD4 count 200 or greater = No (no AIDS). Then you can do Chi-Square. In addition to reporting the Chi-Square results, you need to discuss some descriptive statistics related to your sample (e.g., age and race) and for both your IV and DV. Finally, instead of just "plopping in" charts from the SPSS output, you need to, in your narrative, refer to summary results that you also present in APA formatted tables and figures (proper placement of elements is shown below).

Question Would like to check my answer against what you come up with. I’ve included the DATA points on the right hand side. Thank you. ATTACHMENT PREVIEW Download attachment Q12.F.png The Lawnpoke Golf Association (LGA) has established rules that manufacturers of golf equipment must meet for their products to be acceptable for LGA events. BatOutaHell Balls uses a proprietary process to produce balls with a mean distances of 295 yards. BatOutaHell is concerned that if the mean distance falls below 295 yards, the word will get out and sales will sag. Further, if the mean distance exceeds 295 yards, their balls may be rejected by LGA. Measurements of the distances are recorded in DATA. At a = 0.05, test the no action hypothesis that the balls have a mean distance of 295 yards. 0 The test statistic is 3.003 and the critical value is 2.101, therefore the test statistic is greater than the critical value of 2.101 and the null hypothesis is rejected. The distance is not 295 yards. 0 The test statistic of 2.238 is greater than the critical value of 2.101, therefore H0 is rejected. It is reasonable to assume that the distance is not 295 yards. 0 The test statistic is 1.297 and the critical value is 2.101, therefore the test statistics is less than the critical value and the null hypothesis is not rejected. The distance is about 295 yards. 0 The test statistic of 1.908 is less than the critical value of 2.101, therefore H0 is not in the area of rejection. It is reasonable to assume that the distance is about 295 yards. Test H0: u = 295. HA: [1 at 295 Yards 298 273 284 292 275 309 292 302 311 287 279 282 297 283 305 299 294 295 285

Perform an event study with the data given for the

Question Perform an event study with the data given for the 6 dividend omission events (the data is given in the file “dividend omission permno”). The Microsoft Excel text file contains both the permnos and the event dates. Eventus requires that you upload this file in step 1 of Eventus. Once you have performed the event study, report the following information:1.What are the estimates from the market model for alpha and beta for each of the 6 securities/events?2.Identify date and mean abnormal return (derived from the market model) for all dates where there is evidence to reject the null hypothesis that the mean abnormal return equals zero. State the level of statistical significance, 10% level, 5% level, or 1% level.Hint:Note that you will report the strongest statement you can correctly make about statistical significance. For example, if the p-value is .03, then report “statistically significant at the 5% level.”3.Eventus will permit you to select more than one event window. Examine event windows of different duration. For example, examine event windows beginning as early as day -10 and ending as late as day 10. Also, examine windows beginning prior to the event date and ending on the event date (day 0) as well as event windows beginning with the event date and ending after the event date. Examples include event windows (-10, 10), (-5,0), (0, 5), (-1,0), (0, 1), (-1, 1), and (-2, 2). Identify the event window and the mean cumulative abnormal return derived from the market model for all event windows where there is evidence to reject the null hypothesis that the mean CAR equals zero. State the level of statistical significance.4.If the mean CAR is negative, how do market participants view dividend omissions?For all of your tests for statistical significance, use the Portfolio Time Series (CDA) test statistic which employs the test (t-test) with which you are familiar.Data
