In 2015, a survey found that 38% of Americans were supportive of online education for elementary and secondary education. With the increase in contagious viruses, it is of interest if this proportion has changed. In a 2019 poll, 51% of 1028 Americans were supportive of online education for elementary and secondary education. At the 10% significance level, do the data provide sufficient evidence to conclude that the percentage of all American adults who support online education for elementary and secondary education has changed from what was believed in 2015? Choose the choice that gives the null and alternative hypothesis.
