Construct and interpret 95% confidence intervals for the difference in mean pain intensity at 14 days after treatment. (Use μVertebroplasty − μPlacebo. Round your answers to two decimal places.) -1.188 Correct: Your answer is correct. to .788 Correct: Your answer is correct. Interpret the interval. There is a 95% chance that the true mean pain intensity 14 days after treatment for the vertebroplasty treatment is directly in the middle of these two values. There is a 95% chance that the true difference in mean pain intensity 14 days after treatment for the vertebroplasty treatment and the fake treatment is directly in the middle of these two values. We are 95% confident that the true mean pain intensity 14 days after treatment for the vertebroplasty treatment is between these two values. We are 95% confident that the true mean pain intensity 14 days after treatment for the fake treatment is between these two values. We are 95% confident that the true difference in mean pain intensity 14 days after treatment for the vertebroplasty treatment and the fake treatment is between these two values. Correct: Your answer is correct. Construct and interpret 95% confidence intervals for the difference in mean pain intensity at 1 month after treatment. (Use μVertebroplasty − μPlacebo. Round your answers to two decimal places.) Incorrect: Your answer is incorrect. to Incorrect: Your answer is incorrect.
