REQUIRED: 2.1 Based on the background information provided above, specify the independent variables (IV) and dependent variable (DV) of the investigation, and state their respective levels of measurement. 2.2 Formulate the null and alternative hypotheses for the investigation. 2.3 The validity of the parametric analysis is dependent upon three main assumptions that must be made of the data that if not met will lead to an inflation of Type I error rates and a reduction in power. According to the background information: In the preliminary phase of the datav

analysis, the analyst established that parametric assumptions were met

Critically discuss the three main parametric assumptions that were

assessed by the analyst and how they were assessed. 2.4 Based on the output, specify the TWO statistical tests employed in the data analysis and discuss whether or not both are necessary for the investigation. 2.5 Provide a comprehensive interpretation of the output and highlight the primary finding from the investigation. 11.85 12.46 12.69 14.15 14.54 .243 (4 marks) (2 marks) (4 marks) (4 marks) (6 marks)

Study the information provided below and answer the following questions. An equity analyst recommended to you five companies listed on the Johannesburg Stock Exchange (JSE) to be included in a prospective investment portfolio. Each of the companies operates in one of five sectors, namely: Investec Plc (Financials), PPC Limited (Industrials), Tiger Brands Limited (Consumer goods), BHP Group Limited (Basic Materials), and MTN Group Limited (Telecommunications). The analyst made available the annualised returns of the stocks of each of the five companies over the 2010 - 2022 financial years as shown in the Table 2 below: Table 2: Annualised returns of the stocks of five combanies over the 2010 - 2022 financial vears The equity analyst undertook a quantitative analysis of the annualised returns of the stocks with the aim of determining whether the performance of the stocks over the 2010-2022 period was significantly different across the five companies. At the end of the analysis, the worst performing stock was to be replaced with another stock from the same sector as the replaced stock. The analyst used IBM SPSS Statistics version 27 to analyse the data. In the preliminary phase of the data analysis, the analyst established that parametric assumptions were met and in the subsequent analysis, the output depicted in Figure 2.1 to Figure 2.4 below was generated.
