A tech company noticed that teams using agile methodology complete projects 20% faster than teams using waterfall methodology. However, agile teams also report 30% more instances of scope changes during development. What is the MOST justified inference?
Answer: Faster completion under agile may come partly from flexibility in adjusting project scope
The correlation between faster completion and more frequent scope changes suggests agile's speed advantage may partly result from its ability to modify requirements during development.
A hospital introduced a hand-hygiene monitoring system with electronic sensors. Hand-washing compliance rose from 40% to 85% in the first month, but hospital-acquired infection rates dropped by only 8%. Which inference is MOST reasonable?
Answer: Factors beyond hand hygiene contribute significantly to hospital-acquired infections
A dramatic increase in hand hygiene with only a modest decrease in infections suggests that multiple transmission pathways beyond hand contact contribute to hospital infections.
A nationwide survey found that 78% of parents believe their children spend too much time on screens, yet the average household in the survey had five internet-connected devices. What can MOST reasonably be inferred?
Answer: There is a gap between parents' stated concerns and the digital environment they provide at home
The contrast between parental concern and high device availability suggests a disconnect between what parents express as ideal and the reality they maintain at home.
A school district that switched to later start times for high schools saw attendance improve by 12% and tardiness decrease by 35%. Elementary schools in the same district, which kept their original start times, saw no change. Which inference is MOST supported?
Answer: The attendance and tardiness improvements in high schools are likely related to the schedule change
The improvement in high schools but not elementary schools, where no change was made, supports the inference that the schedule change drove the high school results.
An online retailer found that customers who use their mobile app spend an average of $120 per month, while website-only customers spend $85 per month. The company concluded that the app drives higher spending. Which inference represents the STRONGEST challenge to this conclusion?
Answer: Customers who download a shopping app may already be more engaged and likely to spend more
Customers who take the extra step of downloading an app may already be more committed shoppers, meaning the app may not cause higher spending but instead attract those who already spend more.
A city installed speed cameras on its busiest highway. Speeding violations on that highway dropped by 50%, but speeding violations on parallel side streets increased by 30%. What is the MOST supported inference?
Answer: Some drivers shifted their routes to avoid the monitored highway
The simultaneous decrease on the monitored road and increase on nearby alternatives strongly suggests drivers changed routes to avoid detection rather than changing their speeding behavior.
