The Pew Internet and American Life Project surveyed 2227 adults, asking them about their texting habits. Among men, the mean number of text messages sent per day was 40.9, and among women it was 42.0. Assume that 1085 men and 1142 women were sampled, and that the standard deviations were 56.5 for the men and 51.4 for the women. Can you conclude that the mean number of text messages differs between men and women? Use the α = 0.05 level of significance.
