In a random sample of 98 children who received antibiotics for throat infections, 25 did not have a throat swab. At = 0.05, is this a statistically significant reduction over last year’s national rate of 40 percent?

Calculate the critical value. (A negative value should be indicated by a minus sign. Round your answer to 3 decimal places.)

Calculate the test statistic. (A negative value should be indicated by a minus sign. Round your answer to 2 decimal places.)
