Research question: Is the mean score in the population different from 90 points?   H0: μ = 90Ha: μ ≠ 90   The hypotheses above were tested using data from a random sample. Descriptive statistics are presented in the following table:   Descriptive Statistics N Mean StDev   Compute Cohen’s d for the difference between the observed sample mean and hypothesized population mean. Round your final answer to three decimal places.

H0: p = 0.5 Ha: 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?
