What does this result mean? The t ratio of -0.65 represents the smallest relative difference between the pretest and 3 months outcomes. This ratio does not have an asterisk next to it in the table which according to the footnotes the asterisk is said to represent p < 0.05 the least stringent acceptable value for statistical significance. 4. What are the assumptions for conducting a t-test for dependent groups in a study?
D. level of significance is to the test statistic. You performed a right tailed hypothesis test and your sample gave you a test statistic in the left tail. Which of the following is considered the appropriate next step in this hypothesis test? A. Fail to reject the null.
• Question 1 10 out of 10 points Decision makers who try their best for rationality but are constrained by limited information and processing abilities are referred to as: Answer Selected Answer: boundedly rational. Correct Answer: boundedly rational. • Question 2 10 out of 10 points Utility is a(n) _____ measure of wellbeing of a person. Answer Selected Answer: ordinal Correct Answer: ordinal • Question 3 10 out of 10 points Carla had received very low annual return from her investment portfolio comprising of stocks of five companies for two years. Her decision to continue holding the same portfolio of assets will be an example of: Answer Selected Answer: systematically missed opportunities.
That is, if one is true, the other must be false. Formulate an analysis plan. The analysis plan describes how to use sample data to evaluate the null hypothesis. The evaluation often focuses around a single test statistic. Analyze sample data.
* Cost of Equity: * Beta: she used the average beta of the last 5 years, which is also acceptable. However, we decide to use the Bayesian beta calculated with the firm’s present beta as a measure of the future beta assessing for future risk. * Risk-free rate: from the investor’s perspective, we conclude that a 10-year holding period would be more realistic estimate than 20-year. Therefore, we decide to use 10-year U.S. Treasury yield as our risk-free rate in this case. * Risk premium: using the geometric mean from 1926 to 1999 might be problematic, since the risk premium of recent decades is obviously lower than earlier (stated in the lecture).

In simple terms, statistical power is the likelihood that a researcher will discover an effect of a certain size in a statistical test no matter how small. The analysis of the power of statistical test enables the researcher to estimate the ability of the entire research work to detect a meaningful effect. Technically, statistical power is the probability that the researcher will avoid a Type II error. Type II errors are false negatives where the test result indicates there is no effect when a real effect exists. The analysis of statistical power is done either retrospectively, which means post hoc, or prospectively, which implies a priori.
A visual representation of the market shares can be found in Appendix I. To determine if the Chevrolet Volt’s pre-tax profits are average, above or below average its relative market share should be calculated. The market share of the Leaf, Prius and Lexus are used to calculate the relative market share of the Volt. Generally, if the relative market share of company is 50, it means that its pre-tax profits are average. However, The Chevy volts relative market share is only 5.24 %, therefore its pre-tax profit compared to its 3 main competitors is well below average.
