1. The national population mean hours spent on social media per week is 7.2 hours. The population standard deviation hours spent on social media is 8 hours. Suppose a researcher takes a sample of 36 people. Use this information to answer the followingquestions.
   1. What is the sampling distribution for the sample mean hours spent on social media? That is, whatisthedistribution,expectedvalue,andstandard deviationforthesamplemean.
