Answer Exam Paper - Essay Example Take interest in the F-stat and P-value. They are the only bits you need to validate any investigation (hypothesis). If asked to calculate physically, F=Mean sum of squares (between groups)/ MS (within groups). You realize that for this question we treat the Variation within groups as the ‘error group’, thus Error Sum of Squares (SSE) where we have SS (within groups) and Mean Error sum of squares (MSE).Now when you are required to use F-Stat to validate your test, you got to have two values of it. The first one you compute as in the case shown in the table below (the ANOVA). It is called the computed value of F or F-Computed (you went the long ANOVA way to compute it). To get the second one it is really easy, especially when you’ve got the table values. Take the degrees of freedom in the row you want to test AGAINST THE TOTAL, very important, and bear in mind the level of significance. For example here we shall have F (3, 79, 0.05). They flow in the order Numerato r, Denominator and Level of Significance (LoS). You call this the F-tabulated (derived from the tables). If F-computed>F-tabulated, reject the H0. The P-Value works slightly different. If the P-Value is much less than the Level of Significance, you reject the null hypothesis. ... e of Variation SS df MS F P-value F crit Between Groups 11115.24 3 3705.079 22.74625 1.31E-10 2.724944 Within Groups 12379.45 76 162.8875 Total 23494.69 79 Â   Â   Â   Â   a) F-Statistic= 22.74625 P-Value= 1.31?10-10 b) Let ?i denote the average service time for outlet i. H0: ?1= ?2= ?3= ?4 In order to test the hypothesis on means, the null hypothesis becomes the proposition that all means are equal. Thus by default, anything different will form the alternative hypothesis. c) Yes I would reject the null hypothesis at 5% Level of Significance. This is because the P-Value is smaller than the Level of significance. In order to answer this question, you either refer to the P-value or the F-statistic, when you have both it is your choice. Your Professor was good enough to facilitate your having both. Remember that if the P-value is smaller than the LoS, you reject H0; and if F-computed is greater than F-tabulated, you reject. THAT IMPLIES THAT P-VALUEF-TABULATED. IN BOTH CASES YOU REJ ECT THE NULL HYPOTHESIS. 1.31?10-10

Fin Mgt Final Project - Essay Example We found that, though the two companies are quite profitable, Blue Scope Steel Limited is more profitable as we recommend those currently holding its stock should hold or buy more. Our recommendation is for our company to invest in this particular company. Globalization, the new information technology, and deregulation of financial markets and the quest for market dominance have eased the provision and search of finance. Today, millions of shares are traded every day on the world’s stock markets. (Penman, 2003). Most often, investors see valuation as the first step toward intelligent investing. It has been argued (e.g. Penman 2003) that an investor can make informed decisions about where to invest once the value of shares are determine based upon the fundamentals. This is so because, without this value investors can either buy high or sell low Investors who trade on these stocks are often forced to ask themselves whether they are buying or selling at the right price. (Penman, 2003). Faced with too much information, Investors at times get confused with no clear indication of what the true prices of stocks should be. (Penman, 2003). Under such circumstances, the investor either make decision based on his or her instinct, such investors according to Penman (2003) are intuitive investors while others who make their decision based on capital market efficiency are referred to as passive investors (Atrill & Elliot2005). Penman, (2003) further argues that in making their decision, passive investors assumed that the market price is a fair price of the shares quoted. These investment mechanisms appear to be very simple, as they do not require much effort. (Penman, 2003: pp 3). How ever that is not the case as neither passive nor intuitive investor turn to be better off in the face of their decision. This is so because these sets of
