For Chapter Nine, Ashley and I had to complete a statistic sample on how long 30 Fowler students spend on Facebook a day, and then compare it to the world average. We picked our 30 students from only the Junior and Senior class, gave them a number, and then used a random number generator to pick who we ask. We chose 15 from both the classes and then went out and got our data. We had to calculate a lot of items, but the main calculations were about the Sample Mean, Sample Standard Deviation, Null hypothesis, Alternate hypothesis, and the Level of significance. We first listed all our answers, then below we explain how we received them, which are bolded for organization. Below is our data set (in minutes) from which we calculated our answers.
