A pediatrician suggests that the on average elementary aged children spend 14 hours weekly playing video games. 60 children are used in a sample and it is found that the average is 17 hours weekly with a standard deviation of 2.
Conduct hypothesis test at a 0.025 significance level to check if the pediatrician’s suggestion is true.
μo = hypothesized hours of video games played per child = 14 hours
(x ) ̅= sample hours found that children spend gaming = 17 hours
σ = population standard deviation = 2 hours
N = sample size = 60
Ho: μ ≤ 14
Ha: μ > 14
