,Q1. A healthcare system's readmission rate for heart failure is 24%, while the
national average is 20%. To determine if this difference is statistically significant,
which test is most appropriate given the data are categorical and independent?
A. Independent samples t-test
B. Chi-square test of independence
C. One-way ANOVA
D. Mann-Whitney U test
Correct Answer: B. Chi-square test of independence
Rationale: The chi-square test is used to compare proportions between two or more
independent groups when data are categorical. Here, the outcome (readmitted or not) and
group (hospital vs. national) are both categorical, making chi-square appropriate. A t-test
or ANOVA would be used for continuous outcomes, and Mann-Whitney is for
ordinal/continuous nonparametric data.
Why Wrong:
A - A t-test compares means of continuous variables, not proportions.
C - ANOVA compares means across more than two groups, not proportions.
D - Mann-Whitney is for comparing distributions of ordinal/continuous data, not
categorical proportions.

Q2. A hospital is monitoring surgical site infections (SSI) using a p-chart. The
centerline is 2.5% and the control limits are set at ±3 sigma. In the last month, the SSI
rate was 4.2%, which is above the upper control limit. Which action is most
appropriate?
A. Adjust the chart to include the new data point and recalculate limits
B. Investigate the process for special cause variation immediately
C. Ignore the point because it is within the 95% confidence interval
D. Change the chart to a c-chart to better monitor rare events
Correct Answer: B. Investigate the process for special cause variation immediately
Rationale: A point above the upper control limit on a control chart indicates special cause
variation, requiring immediate investigation to identify and correct assignable causes.
Recalculating limits to accommodate the point would mask the signal. The point is outside
the expected range, not within any confidence interval. Changing chart type is not
appropriate without first understanding the variation.
Why Wrong:
A - Recalculating limits to include the out-of-control point would hide the special
cause signal.
C - A point beyond the UCL is not within the 95% confidence interval; it signals a
Page 3
, process change.
D - A c-chart is for counts of defects, not rates, and changing chart type is not the first
action.

from Data for Improvement, 2nd Ed., Ch. 5.
Q3. In a regression model predicting patient satisfaction scores (0-100) from age,
length of stay (LOS), and nursing hours per patient day, the coefficient for LOS is
-2.5 with a p-value of 0.04. What is the correct interpretation?
A. For each additional day of LOS, satisfaction decreases by 2.5 points, holding other
variables constant.
B. For each additional day of LOS, satisfaction decreases by 2.5% on average.
C. The model predicts that a patient with zero LOS will have satisfaction of -2.5.
D. LOS is not a significant predictor because the p-value is less than 0.05.
Correct Answer: A. For each additional day of LOS, satisfaction decreases by 2.5
points, holding other variables constant.
Rationale: In multiple regression, the coefficient represents the change in the dependent
variable for a one-unit change in the predictor, holding all other predictors constant. A
negative coefficient of -2.5 indicates a decrease of 2.5 points in satisfaction per additional
day of LOS. The p-value <0.05 indicates statistical significance, not insignificance.
Why Wrong:
B - The coefficient is in points, not percentage change.
C - The intercept, not the coefficient, represents the value when all predictors are zero.
D - A p-value less than 0.05 indicates significance, not the opposite.

Q4. A healthcare organization plans to implement a predictive model for early sepsis
detection. The model has an AUC of 0.85, sensitivity of 90%, and specificity of 70%.
At a prevalence of 5%, what is the positive predictive value (PPV)?
A. 13.6%
B. 24.2%
C. 37.5%
D. 64.3%
Correct Answer: A. 13.6%
Rationale: PPV = (sensitivity × prevalence) / [(sensitivity × prevalence) + ((1 - specificity)
× (1 - prevalence))]. = (0.90 × 0.05) / [(0.90 × 0.05) + (0.30 × 0.95)] = 0.045 / (0.045 +
0.285) = 0..33 = 0.136 = 13.6%. The low prevalence drastically reduces PPV
despite high sensitivity and specificity.
