In the Pennsylvania Lottery's Pick 3 game, 3 numbers between 0 and 9 are chosen. One lottery player notices that the number 7 tends to be selected quite often. He takes a random sample of lottery drawings and tests the hypotheses Ho: = .10 vs. Ha: >.10. He concludes that the true proportion of the time that 7 is selected is significantly greater than .10. However, in reality, the true proportion of the time that 7 is chosen is actually .10. What type of decision did he make? Researchers examined a sample of young adults and found that there was a greater likelihood of depression (as measured on a numerical scale), the more time that was spent per day using social media, such as Facebook. What is the response variable in this study? In the Pennsylvania Lottery's Pick 3 game, 3 numbers between 0 and 9 are chosen.
