For healthy adults, the mean pH of arterial plasma (i.e., acidity of the blood) is 7.4. A new drug for arthritis has been developed. Researchers want to conduct a test to see if the new drug has increased the mean pH level of the blood. A random sample of 91 patients with arthritis took the new drug for 3 months. An analysis of the sample data revealed a p-value of 0.019. Step 3 of 3: Use a 1% level of significance to test the claim that the drug has increased the mean pH level of the blood.
