Reading 12: Hypothesis TestingQuestion #1 of 92Question ID: 710147An analyst wants to determine whether the monthly returns on two stocks over the las Reading 12 hypothesis testing questions and answers st year were the same or not. What test should she use. assuming returns are normally distributed?7 A) Paired comparisons test.X B) Difference in means test.X C) Chi-square test.ExplanationPortfolio theory teaches US that returns on two stocks over the same lime period are unlikely to be independent Reading 12 hypothesis testing questions and answers Since both have some systematic risk. Because the samples are not independent, a paired comparisons test is appropnate to test whether the means of tReading 12 hypothesis testing questions and answers
he two stocks' returns distributions are equal. A difference in means test is not appropriate because it requires that the samples be independent.

He takes a sample to determine whether the mean length of Northern Pike Reading 12 hypothesis testing questions and answers in the lake exceeds 18 inches. If the sample t-statistic indicates that the mean length of the fish is significantly greater than 18 inches, when theReading 12 hypothesis testing questions and answers
population mean is actually 17.8 inches, the t-lest resulted in:X A) both a Type I and a Type II error.■J B) a Type I error only.X C) a Type II error Reading 12: Hypothesis TestingQuestion #1 of 92Question ID: 710147An analyst wants to determine whether the monthly returns on two stocks over the las Reading 12 hypothesis testing questions and answers r is failing to reject a null hypothesis when it is actually false.Because a Type I error can only occur if the null hypothesis is true, and a Type II error can only occur if the null hypothesis is false, it is logically impossible for a test to result in both types of error at the same time.Referen Reading 12 hypothesis testing questions and answers cesQuestion From: Session 3 > Reading 12 > LOS cRelated Material:Key Concepts by LOSQuestion #3 of 92Question ID: 413408Which of the following statemeReading 12 hypothesis testing questions and answers

A nonparametric test lends to make minimal assumptions about the population, while parametric tests rely on assumptions regarding the distribution of the population. Both kinds of tests are often used Reading 12 hypothesis testing questions and answers in conjunction with one another.ReferencesQuestion From: Session 3 > Reading 12 > LOS kRelated Material:• Key Concepts by LOSQuestion #4 of 92A Type IReading 12 hypothesis testing questions and answers
