Suppose that we have sampled n observations from a normal distribution and found a 99% confidence interval for a population mean. If the sample size decreases and the confidence level decreases from 99% to 95%, indicate whether the interval will definitely get wider, narrower, or will not be definite either way. Assume that the sample standard deviation remains constant with the new sample size. Group of answer choices We can't say for sure whether it will be wider or narrower. It will definitely get wider. It will definitely get narrower
