UMAT Data Interpretation 2

Question 1

A graph shows that between 2015 and 2020, influenza hospitalizations increased by 15% each year. If there were 1,000 hospitalizations in 2015, approximately how many were there in 2016?

Accepted Answer

1,150

Answer

A 15% increase on 1,000 = 1,000 × 1.15 = 1,150 hospitalizations in 2016.

Question 2

A clinical table shows test sensitivity = 90% and specificity = 85%. If 100 patients have the disease, how many will test positive?

Accepted Answer

90

Answer

Sensitivity measures the true positive rate — 90% of 100 diseased patients = 90 patients will test positive.

Question 3

In a dataset of exam scores (55, 62, 70, 70, 88), what is the mode?

Accepted Answer

70

Answer

The mode is the value that appears most frequently in a dataset; 70 appears twice while all other values appear once.

Question 4

A health survey reports a 95% confidence interval of 45%–55% for a treatment success rate. What does this mean?

Accepted Answer

We are 95% confident the true population success rate lies between 45% and 55%

Answer

A 95% confidence interval means that if the study were repeated many times, 95% of the resulting intervals would contain the true population parameter.

Question 5

A UMAT data question presents two treatment groups: Group A (n=50) with 30 successes and Group B (n=100) with 45 successes. Which group has the higher success rate?

Accepted Answer

Group A

Answer

Group A success rate = 30/50 = 60%; Group B success rate = 45/100 = 45% — Group A has the higher rate.
