The paper, “Pathological Video-Game use Among Youth Ages 8 to 18: A National Study” included the information in the accompanying table about video game playing time for representative samples of 588 males and 590 females selected from U.S. residents age 8 to 18. Carry out a hypothesis test to determine if there is convincing evidence that the mean number of hours per week spent playing video games by females is less than the mean number of hours spent by males. Use a significance level of α = 0.01. Communicate your results.
