statistically significant difference between the means of the two treatment groups on an achievement test.
Which means that the means of two treatments different.
Which of the following is a reasonable conclusion?
Answer:-
b. The difference between the two instructional strategies is meaningful
Because we only conclude that the differences are statistically significant.which one greater or less is not tested.

In a study, researchers randomly assigned 500 people to the “treatment group” and the other 500 to the “control (or placebo) group”. A statistically significant difference was reported between the responses of the two groups with p-value < 0.005. What is the best conclusion? A. There is little evidence that the treatment has any effect. B. Here is strong evidence that the treatment is effective. C. Using a 5% significance level, we can conclude that the treatment was not effective,...

study was conducted examining two different drugs (n=12,000). Both drugs are known for lowering blood cholesterol levels. Drug A outperformed Drug B and the 95% confidence interval estimate of the difference in mean cholesterol level lowering was (18, 41). Which of the following is a reasonable conclusion? There is a 0.95 probability that Drug A will outperform Drug B by at least 23 points in lowering the cholesterol level of any given individual. There is a 0.95 probability that Drug...

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 218 with a standard deviation...
