Organizations are interested in identifying variables that will predict the performance of job applicants. Two known predictors of job performance are personality (i.e., conscientiousness) and years of formal education. Researchers at the University of Arkansas believe that number of previous jobs held by job applicants may also predict performance. However, in contrast to conscientiousness and years of formal education, the researchers anticipate that number of previous jobs held will have an inverse relationship with job performance. To test their ideas, the researchers asked 125 car salespeople from Fletcher Honda to fill out a questionnaire that measured (a) their level of conscientiousness (CONSC) on a 7 point scale (1 = strongly disagree and 7 = strongly agree) where higher scores reflect being more conscientious, (b) years of formal education (EDUC), (c) and number of previous jobs held (JOBS). To measure job performance, the researchers used company records to record the number…

Hospital Beds. The number of hospital beds available in community hospitals is decreasing. Through advancement in care and technology, hospitals are getting more efficient. However, the aging and increasingly obese and diabetic population intensifies the need. The American Hospital Association Annual Survey, published by the American Hospital Association (AHA), gave the number of hospital beds available per 1000 people for each of the 50 states plus the District of Columbia for 2010. Following is a stem-and-leaf diagram of the data. The stems represent units and the leaves tenths (e.g., the first entry is 1.7). How many states (including the District of Columbia) had a. at least three but less than four hospital beds per 1000 people available? b. at least four and a half hospital beds per 1000 people available?

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week. Age Activity 7 4.3 9 3.2 10 1 13 1.5 12 1.2 15 0.8 9 3 12 4 15 1.5 14 1.9 Using excel, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot. Using excel, obtain the simple linear regression linear regression line predicting activity from age. Interpret the intercept and slope of the regression line. By hand, predict the amount of activity for age = 14. By hand, calculate the residual for age = 14 Using excel output, test the null hypothesis that the slope coefficient is zero using the p-value approach.
