In a recent poll of 1000 People from California , 37.3% use Twitter.  It is believed that the true proportion of all Nova Scotians using Twitter is 35%.  

  1. What is the probability that the sample proportion of People from California “Tweeting” in a random sample of 1000 would be within 5% of the population proportion.
  2. What is the probability that in a random sample of 1000 People from California, 37.3% or more “Tweet”?
  3. Given that the statistic in b) was actually observed, do you believe there is evidence that the true proportion of People from California “Tweeting” has increased?

A sample of 1000 people that live in a large city was asked if they believed that the city’s sales tax proposal was warranted. If at least two-thirds of the city’s citizens believe that the sales tax is warranted, then the mayor will take immediate steps to formally propose the tax. The survey responses showed that 692 of the 1000 people surveyed believe that the tax proposal is warranted. Write the appropriate null and alternative hypotheses for the one-tailed test...
