****PLEASE ANSWER ALL QUESTIONS**** Question 12 (1 point) A medical researcher wants to determine if the average hospital stay of patients that undergo a certain procedure is greater than 8.7 days. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≤ 8.7, Alternative Hypothesis: μ > 8.7. If the researcher takes a random sample of patients and calculates a p-value of 0.0942 based on the data, what is the appropriate conclusion? Conclude at the 5% level of significance....

CASE STUDY: DATA WAREHOUSING AT VOLVO Every Volvo car has hundreds of microprocessors and sensors. Their data is used in diagnosis and repair. It is also captured by Volvo, integrated with the company's CRM, dealership and product data stores, and stored for analysis. This enables Volvo to spot design and construction flaws early, enable proactive correction of faults, and see how its cars respond in accidents. Volvo sells about 400,000 cars per year. Each generates 100–150 kB of data per...
