Case Study 3 According to the capital Asset pricing model (CAPM)‚ the risk associated with a capital asset is proportional to the slope obtaining by regressing the asset’s past returns with the corresponding returns of the average portfolio called the market portfolio. (The return of the market portfolio represents the return earned by the average investor. It is a weighted average of the returns from all the assets in the market). The larger the slope of an asset‚ the larger is the risk associated

There are several types of bad statistics that can be seen when looking at statistical data. According to the video “Don’t be fooled by bad statistics” (2010)‚ there are three basic types of bad data consisting of poorly collected data‚ leading questions‚ and misuse of center. Poorly collected data can produce misleading results. For example‚ when a publishing company conducted a phone survey of popular magazines but did so during business hours when stay at home moms were most likely to participate

(-3.5)/1.6396 = -2.1347 Critical Value: Zα/2= Z0.05/2= @qnorm(1-0.05/2)= 1.96 When comparing the test statistic to the critical value: Z=2.1347>1.96‚ we reject the null hypothesis. We can calculate the P-value using the EViews command: Show @tdist (t‚ d.f) In this EViews command‚ t stands for the appropriate test statistic and d.f are the degrees of freedom. The appropriate test statistic was calculated above‚ namely Z=2.1347. For the degrees of freedom‚ we can insert NA+NB-2. Show @tdist (2

Exercise 01 a) Develop a 99 percent confidence interval for the mean selling price of the home. b) Develop a 95 percent confidence interval for the mean distance of the home is from the center of the city. Exercise 02 a) A recent article in Bangladesh Observer indicated that the mean selling price of the homes in the city of Dhaka is more than Tk. 2200. Can we conclude that the mean selling price in the Gulshan area is more than Tk. 2200? Use the 0.01 significance level

Exercise 36 Answers 1. Since the F value is significant‚ based on the p-value of 0.005 which is less than 0.05 which is sufficient to reject the null hypothesis. This suggests that there is a difference in the control and treatment groups. 2. Since the p- value is less than 0.05 and therefor the null hypothesis can be rejected. This presents that the mean‚ difficulty and mobility scores‚ must be different 3. The result was statistically significant with a probability score of p < 0.001.
