HELP ON STATS AND PROBABILITY NEEDED!
Using a random sample from a population, Isla cannot decide if she wants to construct a 95 percent confidence interval for the population mean or a 99 percent confidence interval for the population mean. What is the difference between the two confidence intervals?
Answer choices-
The 95 percent confidence interval will be wider than the 99 percent confidence interval.
The 95 percent confidence interval will not be as wide as the 99 percent confidence interval.
The size of the sample determines which interval is wider.
An unbiased sample determines which interval is wider.
Which interval is wider will depend on whether a z-statistic or a t-statistic is used.
