You are conducting a study to see if the proportion of voters who prefer Candidate A is significantly less than 0.19. You use a significance level of α=0.05.

You obtain a sample of size n=340 in which there are 49 successes. Round your sample proportion to three decimal places.

Perform a hypothesis test.

  • Cleary label and show all four steps of the test as shown in the video.
  • Use only the standard normal table to calculate your probability.
  • Write your conclusion (Step 4) in a complete sentence, using the context of the problem.
