Online dating sites and mobile dating apps have become more popular over the years for American adults, according to the Pew Research Center. In 2013, 11% of adults in the US reported using online sites and mobile apps for dating. In a follow-up Pew Research poll in 2016, that percent jumped up to 15% of American adults. From the 2016 data, a hypothesis test was performed using a significance level of 0.01 and the results are shown in the output below. Based on this, can we conclude that the percentage of American adults who use online sites or mobile apps for dating has increased since 2013? If not, what conclusion would be appropriate based on the sample data?
