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…arrow_forwardHow does analyzing data on these real-world problems aid in problem-solving and drawing conclusions?

- Many research studies have been conducted to examine how different organizations are on implementing knowledge management processes. For example, studies have proved that larger firms have more resources to utilize, and so they have taken more efforts to implement knowledge management processes. The Journal of Business Research (Aug. 2014) published a study discussing the relationship between knowledge management processes and organizational performance. The table below shows the percentage of different size of firms participated in the study. These firms have been classified in terms of number of employees working. Need step-by-step procedure to answer each question. Randomly select one of the participated company from this study. Let x be the number of employees working in the company. Write the probability distribution of this x. What is the probability that the selected company employs more than 50 employees? Find E(x) and σ.

One of the survey questions was, "During the average workday, how many hours do you spend attending meetings?" For the subsample of legal professionals (n = 250), the mean response was M = 2.0 hours, with a sample standard deviation of s = 5.1 hours. The estimated standard error is SM = 0.323.
