Confidence Interval Given. Assume I created a 95% confidence interval for the mean hours studied for a test based on a random sample of 64 students. The lower bound of this interval was 4 and the upper bound was 14. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. (b) Calculate the margin of error for the interval. (c) Calculate the center of the interval. (d)...

Assume we have taken an SRS of 49 UCLA students and calculated a 95% confidence interval for the mean age to be 23 < µ< 27 years. Determine which of the following interpretations are True. Then answer parts i and ii in the space below. A. A 95% confidence interval for the mean age of students at UCLA is 23 to 27. This means that 95% of all students are in this interval. B. A 95% confidence interval for the mean...

Interpret the confidence interval. A random sample of clients at a weight loss center were given a dietary supplement to see if it would promote weight loss. The center reported that the 100 clients lost an average of 34 pounds, and that a 95% confidence interval for the mean weight loss this supplement produced has a margin of error of +10 pounds. 0 95% of the people who use this supplement will lose between 24 and 44 pounds. 95% of...

An article describes several studies of the failure rate of defibrillators used in the treatment of heart problems. In one study conducted by the Mayo Clinic, it was reported that failures were experienced within the first 2 years by 12 of 97 patients under 50 years old and 13 of 363 patients age 50 and older who received a particular type of defibrillator. Assume it is reasonable to regard these two samples as representative of patients in the two age...
