Listed below are the lead concentrations (in mu g divided by g) measured in different Ayurveda medicines. Ayurveda is a traditional medical system commonly used in India. The lead concentrations listed here are from medicines manufactured in the United States. The data are based on the article “Lead, Mercury, and Arsenic in US and Indian Manufactured Ayurvedic Medicines Sold via the Internet,” by Saper, et al., Journal of the American Medical Association, Vol. 300, No. 8.
3, 6.5, 6 5,.5, 20.5, 7.5, 12, 20.5, 11.5, 17.5
Use a 5% significance level to test the claim that the mean lead concentration for all such medicines is less than 14 mu g divided by g .
Follow Up
Suppose we had an error in our data that was caused by a typo.
Change the first occurrence of 20.5 to 2.05. Would this change our
conclusion? What is the updated p-value?
p-value = ____________.
