The Society for Human Resource Management (SHRM) collaborated with Globoforce on a series of organizational surveys with the goal of identifying challenges that HR leaders face and what strategies help them conquer those challenges. A 2016 survey indicates that employee retention/turnover (46%) and employee engagement (36%) were cited as the most important organizational challenges currently faced by HR professionals. 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, SHRM and Globoforce showed that 326 (77%) of the 423 small organizations have employee retention programs as compared to 167 (87%) of the 192 large organizations a.

The data are stored in the accompanying table Use the​ least-squares method to determine the regression coefficients b0 and b1.

In 2015, over 30,00030,000 Americans died from opioid overdoses, and the number of inpatient stays and emergency visits to hospitals related to opioids increased dramatically compared to previous years. The National Institutes of Health (NIH) have partnered with the Healthcare Cost and Utilization Project (HCUP) to gather data on opioid-related deaths and hospitalizations. These data include information about inpatient stays, emergency department visits, age, sex, income, and opioid-related use. For a given patient admitted to a hospital for an opioid-related event, identify which of these events are disjoint. A) The patient was 62 years old. B) The patient did not visit the emergency room. C) The patient was male. D) The patient was admitted to a large metropolitan hospital. E) The patient's case was critical and they were admitted to the emergency room.

A mail-order catalog business that sells personal computer supplies, software, and hardware maintains a centralized warehouse for the distribution of products ordered. Management is currently examining the process of distribution from the warehouse and has the business objective of determining the factors that affect warehouse distribution costs. Currently, a handling fee is added to the order, regardless of the amount of the order. Data that indicate the warehouse distribution costs and the number of orders received have been collected over the past 24 months and can be seen below:     Months Distribution Cost ($thousands) Number of Orders 1 52.95 4015 2 71.66 3806 3 85.58 5309 4 63.69 4262 5 72.81 4296 6 68.44 4097 7 52.46 3213 8 70.77 4809 9 82.03 5237 10 74.39 4732 11 70.84 4413 12 54.08 2921 13 62.98 3977 14 72.30 4428 15 58.99 3964 16 79.38 4582…

The hospital readmission rate is often considered an indicator of an undesirable patient outcome. Youquality improvement team is located at a metropolitan hospital that serves a large population. The quality improvement team is conducting a study pertaining to readmissions, smoking and number of drugs administered to admitted patients with congestive heart failure (CHF). The team is interested in reducing the number of readmissions among patients discharged with a principal diagnosis of CHF.  The team believes that the high admission rate is due to the difficulty that these patients have in controlling the number of drugs that they typically take. The team believes that by improving patient/family education regarding drug administration, the readmission rate could be reduced. Thus, they have developed the screen “CHF patients taking three or more drugs” to identify these patients before discharge. To evaluate the effectiveness of the measure, the team conducts a study on all CHF…
