Suppose you are testing whether there is a statistically significant difference in depression level between a treatment and placebo group. You find a p-value of p=0.90. Do you reject or fail to reject the null hypothesis of no difference between groups? Why? Explain.
Question 12 2 pts If a researcher reports a “statistically significant difference” between two groups after conducting an independent-samples t test, this implies that: Cohen's d is at least 0.50. the difference between the two groups is unlikely to have occurred by chance if the null hypothesis is true. the difference between the two groups is unlikely to have occurred by chance if the null hypothesis is false. there is a large difference between the two groups.
Dr. Cribari would like to determine if there is a statistically significant difference between her two Math 2830 classes. To make this comparison she will compare the results from exam 1. Class one had 35 students take the exam with a mean of 82.6 and a population standard deviation of 1.41. Class two had 32 students take the exam with a mean of 84 and a population standard deviation of 3.63. Can Dr. Cribari conclude that there is difference in...
