In determining the best companies to work for, a number of variables are considered, including size, average annual pay, and employee turnover rate. Moreover, employee surveys are conducted to assess aspects of the organization's culture, such as trust and openness to change. In an attempt to determine what affects turnover rate, a sample of 33 companies was randomly selected, and data were collected on the average annual bonus and turnover rate (%) for 2008. In addition, a questionnaire was administered to the employees of each company to arrive at a trust index (measured on a scale of 0-100). Below are the multiple regression results.

- A researcher wants to investigate whether mindfulness training improves ability for employees to notice positive experiences in the workplace, and if this differs by gender and/or disposition. Employees were randomly assigned to one of two groups: no training or a half-day session. Gender was categorized as male or female. Disposition was categorized as follows: optimist, pessimist or realist. Ability to notice positive experiences in the workplace was quantified using a Likert-based ambulatory assessment. A factorial design was used to analyze the data.

Question: What is the dependent variable?arrow_forwardThe Minnesota Multiphasic Personality Inventory (MMPI) is one of the most frequently used personality tests in psychology. The current standardized version, the MMPI-2, is used by trained professionals to assist in identifying personality structure and psychopathology. A forensic psychologist is interested in whether she can identify potential serial killers by their MMPI profiles. She is particularly interested in the Paranoia and Infrequency scales of the MMPI. She interviews 12 people who have already been identified as serial killers. Their scores on the Paranoia scale are recorded here: 69 84 56 89 47 63 86 58 74 35 71 60 ll Which of the following is a possible value for the range?arrow_forward

According to a study released by PwC, 38% of surveyed business and IT executives reported phishing scams at their institutions.Source: Data extracted from “Toward new possibilities in threat management,” PwC, 2017 pwc.to/2kwhPJv. a. If you conduct a follow-up study to estimate the population proportion of business and IT executives reporting phishing scams at their institutions, would you use a p of 0.38 or 0.50 in the sample size formula? b. Using your answer in part (a), find the sample size necessary to estimate, with 95% confidence, the population proportion to within 0.03.arrow_forwardAccording to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in 2007 were for identity theft.
