A given apartmentcomplexhas500 apartments. Investigatorswanttorandomtychoose50 apartments from around thecomplexand test thoseapartments. Theapartmentswill betagged H if their radon levelis above4 pCi/Land Lif it is at or belowthis value. b. Define the parameter of interest and state the null and alternative hypotheses used for testing theapartments.
