Consider the situation described in the image above. The result of this is that their confidence interval will now be: Group of answer choices about 3 times wider pretty much unchanged about 1/9 as wide about 1/3 as wide about 9 times wider

The probability that a 95% confidence interval includes the parameter of interest is 0.95.Group of answer choicesTrueFalse
