Problem 1: Hypothesis testing for proportions. Conduct all hypothesis tests at the alpha level of 0.05. From a random sample of 900, 52% of the students indicated they agree that many of the world's children had been vaccinated against measles.
Problem 2: Test the hypothesis that a majority (a 50%) believed that many of the world's children have been vaccinated against measles?
Problem 3: State the null and alternate hypotheses:
- Calculate the SE. z-score and p-value. Display all those values.
- Write a conclusion for your hypothesis test of proportions.
