Question

Please answer the following:

I. Compete the table. Level of Significance, a (in decimal or %) Confidence Level (in %) 1. 1% 2. 0.05 3. 98% 4. 0.01 5. 80% II. Compute the following. 1. A random sample is drawn from a population of known standard deviation 11.3. Construct a 90% confidence interval for the population mean based on the information given: a. n = 36 X= 105.2 b. n = 100 x= 105.2 2. A random sample is drawn from a population of unknown standard deviation. Construct a 99% confidence interval for the population mean based on the information given: a. n = 49 X= 17.1 O = 2.1 b. n = 169 X= 17.1 O = 2.1 3. A random sample of size 144 is drawn from a population whose distribution, mean, and standard deviation are all unknown. The summary statistics are x = 58.2 and o = 2.6. Construct a 90% confidence interval for the population mean µ.
