1. Find the far left in the 99% confidence interval for the mean of a sample with population mean = 95, standard deviation = 4, and sample size n = 46. Assume that the sample comes from a population with normal distribution. Round the result to two decimal places.

Answer:

2. Use the same data as the previous question:

Find the far right in the 99% confidence interval for the mean of a sample with population mean = 95, standard deviation = 4, and sample size n = 46. Assume that the sample comes from a population with normal distribution. Round the result to two decimal places.

Answer:

3. Find the far left in the 90% confidence interval for the mean of a sample with population mean = 158.15, standard deviation = 15.58, and sample size n = 110. Assume that the sample comes from a population with normal distribution. Round the result to two decimal places.
