A researcher claims that the amounts of acetaminophen in a certain brand of cold tablets have a standard deviation different from the s = 3.3 mg claimed by the manufacturer. Assuming that a hypothesis test is conducted to test this claim, identify the null hypothesis H0 and the alternative hypothesis Ha. Which is correct? H0:  s = 3.3 Ha:  s  ≠ 3.3     H0:   s  ≠ 3.3 Ha:   s = 3.3     Ho:  s > 3.3 Ha:  s < 3.3     H0:  s   3.3  Ha:  s > 3.3
