The question involves determining the appropriate formulation of hypotheses for a statistical test. The scenario describes a production manager claiming that the contents of a canned milk product are at least 31 ounces. The task is to test this claim based on sample data.In hypothesis testing, we set up two hypotheses: the null hypothesis ( ) and the alternative hypothesis ( ). The null hypothesis typically represents the status quo or a statement to be tested, while the alternative hypothesis represents what we want to prove or what we suspect is true.1. and : This set of hypotheses tests whether the mean is greater than 31, but it does not align with the manager's claim that the mean is at least 31.2. and : This is the correct formulation. The null hypothesis represents the opposite of the manager's claim (that the mean is less than or equal to 31), and the alternative hypothesis represents the manager's claim (that the mean is greater than 31).3. and .
