Suppose an industrial/organizational psychologist is interested in the relationships between job satisfaction, job performance, and job compensation. She has data from five different countries on the average monthly salaries paid to computer programmers. She begins her analysis by converting all of the salary data into US dollars: Country Average Monthly Salary(US dollars) Standard Deviation(US dollars) Original Currency Italy $1,557 $467.20 euro Hungary $1,468 $220.20 forint the Czech Republic $1,059 $158.80 koruna the United States $4,141 $1,242.20 dollar Latvia $790 $118.60 lat   To appreciate the differences among the countries, she calculates the z-scores for a computer programmer making $1,500 per month. Use the dropdown menus to complete the following table. Country z-score for $1,500 Salary Italy      Hungary      the Czech Republic      the United States      Latvia        Suppose a computer programmer in each of the five countries listed is offered a salary of $1,500 per month. Using the z-scores and assuming that the computer programmer prefers a salary that has a higher relative value, the computer programmer from    will likely be the most pleased with the offer, because a salary of $1,500 per month for this country corresponds to the

1. What is the mean BMI of this population? 2. How do these adults’ BMI value stack up against the rest of the country? 3. Nationally, 47% of adults in the US have hypertension (see the CDC article for more details). Does this population have a significantly lower percentage of adults with hypertension? Use 0.01.

Varatta Enterprises sells industrial plumbing valves. The following table lists the annual sales amounts for a portion of the salespeople in the organization for the most recent fiscal year. a. Compute the mean (in $1000), variance (in $10002), and standard deviation (in $1000) for these annual sales values. Round your answers to the nearest whole number. b. In the previous fiscal year, the average annual sales amount was 290 thousand with a standard deviation of 95 thousand. Discuss any differences you observe between the annual sales amount in the most recent and previous fiscal years. Which of the following is correct? (i) The difference in the mean annual sales amount is very small and is most likely due to random change in demand for these products. (ii) The sample mean annual sales amount and standard deviation for the previous fiscal year were significantly higher. (iii) The sample mean annual sales amount and standard deviation for the previous fiscal year were significantly…

I often hear the opinion that "people who listen to classical music are smarter". In an attempt to test that claim, I gave an IQ test to twO groups of people: Group 1: Students who primarily listen to non-classical music. Group 2: Students who primarily listen to classical music. Their scores are summarized in the following table: Std. Deviation Group 1 111 Group 2 100 98 87 119 108 102 110 10.392 85 105 97 114 93 101 9.142 < Answer the question using a 0.10 level of significance. Select the response which fills-in-the-blank to create a correct sentence: Based on the information and previous parts of the problem, there listen to classical music tend to perform better on an IQ test than those who do not. evidence to support the claim that students who primarily is certain O is not sufficient O is sufficient O cannot be

A statistical program is recommended. Jensen Tire & Auto is in the process of deciding whether to purchase a maintenance contract for its new computer wheel alignment and balancing machine. Managers feel that maintenance expense should be related to usage, and they collected the following information on weekly usage (hours) and annual maintenance expense (in hundreds of dollars). Weekly Usage (hours) Annual Maintenance Expense 13 17.0 10 22.0 20 30.0 28 37.0 32 47.0 17 30.5 24 32.5 31 39.0 40 51.5 38 40.0 (a) Develop the estimated regression equation that could be used to predict the annual maintenance expense (in hundreds of dollars) given the weekly usage (in hours). (Round your numerical values to two decimal places.)
