Table 1 shows the distribution of the opinions of US adults who are married on how long they could go between jobs without any income and still be able to pay all their bills on time. A researcher believes that the distribution of the US adults who are not married is different from those that are married provided in table 1. The researcher randomly selects 250 US adults who are not married and ask them how long they could go between jobs without any income and still be able to pay their bills on time (Table 2). At alpha =0.01, are the distributions different?
