Hypothesis Testing

Suppose we are testing the hypothesis Ho: p = 0.65 versus H1: p > 0.65 and we find the p-value to be 0.02. Explain what this means. Would you reject the null hypothesis? Why?

    Suppose a researcher is testing the hypothesis Ho: p = 0.6 versus H1:p*0.6 and she finds the P-value to be 0.29. Explain what this means. Would she reject the null hypothesis? Why? Choose the correct explanation below. O A. If the P-value for a particular test statistic is 0.29, she expects results no more extreme than the test statistic in about 29 of 100 samples if the null hypothesis is true. OB.

    What is hypothesis testing? How would you explain it to someone who has not had as much statistical experience as you? What is the difference between the null and alternate hypotheses? What does the p-value tell you? When do you reject the null hypothesis or fail to reject the null hypothesis? Explain how collecting data (i.e. convenience sampling, randomly selected sample, etc.) for the samples could impact the ability to generalize your results to the whole population.
