PART 2

In a survey funded by the University of Arizona Psychology Department, 750 of 1000 adult Arizona residents said they did not believe they were a danger when texting and driving. Construct a 95% confidence interval estimage of the proportion of adult Arizona residents who don't believe they are a danger when texting and driving. (Use a zz score of 1.96 for your computations.)

  PART 3
  
  If n=17, (x-bar)=50, and s=4, construct a confidence interval at a 99% confidence level. Assume the data came from a normally distributed population.
  
  Give your answers to one decimal place.
