1.  What do you call the difference between the upper limit and the lower limit of a confidence interval?*A. confidence levelB. margin of errorC. confidence intervalD. length of confidence interval

In a confidence interval, the margin of error is related to what aspect of the interval?*1 pointa. The sample sizeb. The mean of the samplec. The level of confidenced. The range of the data

Which of the following is the width of the confidence interval for the population mean? Group of answer choices (Upper confidence limit – Lower confidence limit) / 2. Upper confidence limit – Lower confidence limit. 2 (Upper confidence limit – Lower confidence limit). Upper confidence limit + Lower confidence limit.

The lower limit of the 95% confidence interval for the mean of the differences is 0.241.Which ONE of the following is the correct way to calculate the value of the upper limit?0.539 + 2 x 0.2980.539 + 2 x 0.980.539 + 0.2980.539 + 0.241

The larger the level of confidence, C, the ______ the confidence interval.smallerlargerNone of the above.
