HPAT Numerical Reasoning and Data Analysis 3

Question 1

A scatter plot shows BMI on the x-axis and fasting blood glucose on the y-axis, with data points clustering along an upward-sloping line. Which conclusion is best supported?

Accepted Answer

Higher BMI is associated with higher fasting blood glucose

Answer

A scatter plot demonstrates association, not causation; the upward trend shows higher BMI is associated with higher fasting blood glucose.

Question 2

Emergency department wait times (minutes) for 10 patients: 10, 22, 8, 45, 12, 18, 35, 9, 25, 16. What is the median wait time?

Accepted Answer

17 min

Answer

Sorted: 8, 9, 10, 12, 16, 18, 22, 25, 35, 45; median = (16 + 18) ÷ 2 = 17 minutes.

Question 3

A hospital budget of $2.5 million is allocated as follows: Personnel 45%, Equipment 25%, Medications 18%, Administration 12%. How much is allocated to medications?

Accepted Answer

$450,000

Answer

Medication allocation = $2,500,000 × 0.18 = $450,000.

Question 4

A clinical trial reports a 95% confidence interval of (1.8 days, 3.6 days) for reduction in hospital stay. Which interpretation is most accurate?

Accepted Answer

We are 95% confident the true mean reduction lies between 1.8 and 3.6 days

Answer

A 95% confidence interval means we are 95% confident the true population mean reduction falls within the stated range.

Question 5

In a cohort study, 200 patients with high cholesterol and 800 without are followed for 5 years. 40 in the high-cholesterol group and 40 in the normal group develop heart disease. What is the risk ratio for heart disease among those with high cholesterol?

Accepted Answer

4.0

Answer

Risk (high cholesterol) = 40/200 = 0.20; risk (normal) = 40/800 = 0.05; RR = 0.20 ÷ 0.05 = 4.0.
