Solution. b. We have to find z critical val …. (b) Provide a 95% confidence interval for the population mean. Now we are to find a 95% confidence interval. We will use the same formula used when constructing the 90% confidence interval. 12/2 MB The sample mean, standard deviation, and sample size remain the same. Only 2/2 will be different.
Part 1: Confidence Intervals . Use the Confidence Interval formula above and calculate the 95% confidence interval for any population mean of your choice. Write down (invent) the sample size (be sure it is 30 or above), the sample mean, and the sample standard deviation. Then, calculate the confidence interval. Remember, you are inventing all ...

Step 1. Now we are to find a 99% confidence interval. We will use the same formula used when constructing the 90% and 95% confidence intervals. xˉ±za/2 nσ The sample mean, standard deviation, and sample size remain the same, Only zα/2 will be different. To find the new value of zα/2, we must first solve (1−α)=0.99 to obtain our value of α.
