A survey by Accenture indicated that 64% of millennials as compared to 28% of baby boomers prefer “hybrid� investment advice-a combination of traditional advisory services and low-cost digital tools-over either a dedicated human advisor or conventional robo-advisory services (computer-generated advice and services without human advisors) alone.
Suppose that the survey was based on 500 respondents from each of the two generation groups.

The Dow Jones Industrial Average (DJIA) and the Standard & Poor's 500 (S&P 500) indexes are used as measures of overall movement in the stock market. The DJIA is based on the price
movements of 30 large companies; the S&P 500 is an index composed of 500 stocks. Some say the S&P 500 is a better measure of stock market performance because it is broader based.
Suppose the closing price for the DJIA and the S&P 500 for 144 days in a certain year are as provided in the file closingprices3.xlsx.
(a) Develop a scatter chart for these data with DJIA as the independent variable. What does the scatter chart indicate about the relationship between DJIA and S&P 500?
The scatter chart indicates there may be a positive linear relationship between DJIA and S&P 500.
The scatter chart indicates there may be no noticeable linear relationship between DJIA and S&P 500.
The scatter chart indicates there may be a negative linear relationship between DJIA and S&P 500.
(b) Develop an estimated linear…
One strategy that may have an impact on employee retention, turnover and engagement is a successful employee recognition program. Surveying small organizations, those with 500 to 2,499 employees, and large organizations, those with
10,000 or more employees, a survey organization showed that 301 (72%) of the 417 small organizations have employee retention programs as compared to 173 (92%) of the 188 large organizations. Complete parts (a) through (c) below.
a. At the 0.05 level of significance, is there evidence of a significant difference between organizations with 500 to 2,499 employees and organizations with 10,000 or more employees with respect to the proportion that have employee recognition

Most advisors suggest that the near-retirees have no more than 50% of their investments in stocks. However, during the huge decline in the stock market in 2008, 15% of near-retirees had 90% or more of their investments in stocks (P. Regnier, “What I Learned from the Crash,” Money, May 2009, p. 114). Suppose you have a random sample of 12 people who would have been labeled as near-retirees in 2008. What is the probability that during 2008: two or more had 90% or more of their investment in stocks?arrow_forward
- An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “How many hours do you work at your job on a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 9.0 hours, with a sample standard deviation of s = 10.4 hours. The estimated standard error is sMM = . Use the following Distributions tool to develop a 99% confidence interval estimate of the mean number of hours legal professionals work on a typical workday.

Suppose that 71% of the companies listing regulations as a challenge also listed the tax burden as a challenge. Assume these percentages hold for all small businesses. 1. If a small business is randomly selected, find the following probabilities: (a) The small business lists either the tax burden or regulations as a challenge. (b) The small business lists either the tax burden or regulations but not both as a challenge.

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. Is there sufficient evidence to suggest there is a linear relationship between SALARY and GMAT at the 5% level of significance? ----------------------------------------------------------------------------------- a = -92040 b = 228 s = 3213 r2 = .66 r =…arrow_forward
