Hop = 0.5 Hai p = 0.5 The hypotheses above were testing using the following sample data. Descriptive Statistics N Event Sample p 95% CI for p 30 18 0.600 (0.406, 0.773) The result was a p value of 0.362, so the researchers had to fail to reject the null hypothesis at the 0.05 alpha level. Which of the following changes would result in a smaller p value? O Conduct a right-tailed test O Decrease the sample size to n=20 Change the alpha level to 0.01 O Obtain a sample with a proportion closer to 0.5
