After years of teaching driver’s education, an instructor knows that students hit an average of μ = 10.5 orange cones with a standard deviation σ = 4.8 while driving the obstacle course in their exam. This is a normal distribution. To test a theory about text messaging and driving, the instructor recruits one student driver to attempt the obstacle course while sending a text message. The individual hits X = 15.9 cones. Do the data indicate that texting has a significant effect on driving? Test with α = .05. Please provide every step of hypothesis testing. (1.5)
