Chapter 10, Problem 17PS
Brand valuations are critical to CEOs, financial and marketing executives, security analysts, institutional investors, and others who depend on well-researched, reliable information needed for assessments, and comparisons in decision making. Milward Brown Optimor has developed the Brand Top 100 Most Valuable Global Brands for WPP, the world’s largest communications services group. Unlike other studies, the BrandZ Top 100 Most valuable Global Brands fuses consumer measures of brand equity with financial measures to place a financial value on brands. The file BrandZTechFin contains the brand values for the technology sector and the financial institute sector in the BrandsZ Top 100 most valuable Global Brands for 2016.
a. Assuming that the population variances are equal, is there evidence of a difference between the technology sector and the financial institutions sector with respect to
b. Repeat (a), assuming that the population variances are not equal.
c. Compare the results of (a) and (b).

However, because 54% of first marriages end in divorce, social scientists have begun investigating influences on marital satisfaction. (Data Source: National Center for Health Statistics.) A counseling psychologist sets out to look at the role of having children in relationship longevity. She decides to measure marital satisfaction in a group of couples with children and a group of childless couples. She chooses the Marital Satisfaction Inventory, because it refers to "partner" and "relationship" rather than "spouse" and "marriage," which makes it useful for research with both traditional and nontraditional couples. Higher scores on the Marital Satisfaction Inventory indicate greater satisfaction. Assume that these scores are normally distributed.

For each school, three variables were measured: (1) GMAT score for the typical incoming student; (2) student acceptance rate (percentage accepted of all students who applied); and (3) starting salary of the typical graduating student. An academic advisor wants to predict the typical starting salary of a graduate at a top business school using GMAT score of the school as a predictor variable. The results of a simple linear regression of SALARY versus GMAT using the 25 data points are shown below.
