Question

CDC's National Asthma Control Program was created in 1999 to help the millions of people with asthma in the United States control their disease. According to a report released in 2010, 35.2% of US adults have intermittent asthma (meaning their asthma is well-controlled without long-term medication). In order to update the report, the CDC sampled 2063 adults and found that 700 of those sampled had intermittent asthma. Test the appropriate hypotheses to determine if the percentage of US adults with intermittent asthma has changed from the value reported by the CDC. Use a significance level of 0.10. Ho: p = 0.352 Ha: p ≠ 0.352 α = 0.10 Test Statistic: z = (p̂ - p) / √(p(1-p)/n) (Note: round the test statistic to two decimal places) probability = 0.2272 decision: Fail to reject H₀ At the 0.10 level, there is not significant evidence to conclude the percentage of US adults with intermittent asthma is different than 35.2%.

Ho: p = 0.352
Ha: p ≠ 0.352
α = 0.10

Test Statistic: z = (p̂ - p) / √(p(1-p)/n) (Note: round the test statistic to two decimal places)
probability = 0.2272
decision: Fail to reject H₀

At the 0.10 level, there is not significant evidence to conclude the percentage of US adults with intermittent asthma is different than 35.2%.
