Based on your P-value, what is the conclusion if we test at the 0.05 level of significance? There is evidence to conclude that the mean time of Facebook visits has not increased. There is not enough evidence to conclude that the mean time of Facebook visits has not increased. This is not enough evidence to conclude that the mean time of Facebook visits has increased. There is evidence to conclude that the mean time of Facebook visits has increased.
