A statistician claims that the proportion of students who will vote for Mr. K to be the next president is 0.54 with the standard deviation of 0.3.

  1. Identify the hypothesis test
  2. If 1000 students are randomly selected and 455 of them will not vote for Mr. K, what is the P-value? What can you conclude based on 5% significant level?
  3. Construct a 95% Confidence Interval
  4. If Mr. K is ended up losing the election, does this make sense? Why or why not?

An FM rock station claims that 85% of all its listeners are college students. A statistician decides to test this claim against the suspicion that the percentage is too high. A random sample of 2000 listeners is selected from the population of all listeners and it is determined that 1655 are college students. Perform a hypothesis test to answer the question: Do the sample results support the statistician’s claim at α = 1 %? I. State the hypotheses (in words...
