What type of question is this-estimation or hypothesis? What type of study is this sample data or experiment data? What type of data is this? Univariate or bivariate? Categorical or Numerical? How many samples or treatments? 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. Sample Sample Size Sample Mean (hours per week) Sample Standard Deviation Size (hours per week) Females 590 9.2 10.2 Males 588 16.4 14.1 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.
