Question 1

A study found that employees who participate in regular team-building exercises report higher job satisfaction. Based on this information, what is the probability of the following inference: Team-building exercises directly cause increased job satisfaction.

Accepted Answer

Insufficient Data

Answer

The study shows a correlation between team-building and satisfaction, but other factors such as workplace culture or management style could also contribute, making the causal claim unsupported by the data alone.

Question 2

A city implemented a new public transit system last year. Since then, traffic congestion during rush hours has decreased by 15%. What is the probability of the inference: The new transit system is responsible for the reduction in traffic congestion.

Accepted Answer

Probably True

Answer

While other factors could contribute, the timing and magnitude of the decrease make it probably true that the new transit system played a significant role in reducing congestion.

Question 3

Research indicates that 80% of successful entrepreneurs read at least one book per month. From this, what is the probability of the inference: Reading frequently will make a person a successful entrepreneur.

Accepted Answer

Probably False

Answer

The statistic describes a habit common among successful entrepreneurs but does not establish that reading alone leads to entrepreneurial success, as many other factors are involved.

Question 4

A hospital reported that patients who received a new experimental drug showed a 40% faster recovery rate compared to those on standard treatment. What is the probability of the inference: The experimental drug is more effective than the standard treatment.

Accepted Answer

Probably True

Answer

A 40% faster recovery rate provides strong evidence that the drug is likely more effective, though additional controlled studies would be needed for certainty.

Question 5

In a survey of 500 college students, 70% said they prefer online learning to in-person classes. What is the probability of the inference: The majority of all college students in the United States prefer online learning.

Accepted Answer

Insufficient Data

Answer

A survey of 500 students from unknown institutions cannot reliably represent the preferences of all U.S. college students without knowing the sampling methodology.
