According to the Pew Research Center, the proportion of the American population who use only a cellular telephone (no landline) is 0.42. Jason conducts a survey of fifty 20- to 24-year-olds who live on their own and finds that 18 do not have a landline to their home. Does this provide sufficient evidence to conclude that the proportion of 20- to 24-year-olds who live on their own and don't have a landline is greater than 0.42? Use an a-0.10 level of significance.
Does this provide sufficient evidence to conclude that the proportion of Americans without landlines has decreased?
