To combat antibiotic resistance, the Quality Improvement
Consortium recommends a throat swab to confirm strep throat before
a physician prescribes antibiotics to children under age 5. In a
random sample of 98 children who received antibiotics for throat
infections, 35 did not have a throat swab. At α = 0.05, is this a
statistically significant reduction over last year’s national rate
of 40 percent?
