A company surveyed adult Americans about their consumer debt. The article reported that 48% of millennials (those born between 1980 and 1996) and 62% of Gen Xers (those born between 1965 and 1971) did not pay off their credit cards each month, and therefore carried a balance from month to month. Suppose that these percentages were based on representative samples of 450 millennials and 300 Gen Xers. LUSE SALT Is there convincing evidence that the proportion of Gen Xers who do not pay off their credit cards each month is greater than this proportion for millennials? Test the appropriate hypotheses using a significance level of 0.05. (Let p, be the proportion of Gen Xers who do not pay off their credit cards each month, and p, be the proportion of Millennials who do not pay off their credit cards each month.)

Transcribed Image Text:A company surveyed adult Americans about their consumer debt. The article reported that 48% of millennials (those born between 1980 and 1996) and 62% of Gen Xers (those born between 1965 and 1971) did not pay off their credit cards
each month, and therefore carried a balance from month to month. Suppose that these percentages were based on representative samples of 450 millennials and 300 Gen Xers.
Is there convincing evidence that the proportion of Gen Xers who do not pay off their credit cards each month is greater than this proportion for millennials? Test the appropriate hypotheses using a significance level of 0.05. (Let p, be the
proportion of Gen Xers who do not pay off their credit cards each month, and p₂ be the proportion of Millennials who do not pay off their credit cards each month.)
