Living with parents: the pew research center reported that 36% of american millennials (adults ages 18–31) still live at home with their parents. a group of students wants to conduct a study to determine whether this result is true for students at their campus. they survey 300 randomly selected students at their campus and determine that 43% of them live at home with their parents. with this data, they test the following hypotheses. h0: of millennial students at their campus, 36% live at home with their parents. ha: more than 36% of millennial students at their campus live at home with their parents. in order to assess the evidence, which question best describes what we need to determine? if we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 36%? if we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 43% or more? if we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 36%? if we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%? if we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 43%?
