ASK YOUR TEACHER You may need to use the appropriate appendix table or technology to answer this question A simple random sample of 80 items resulted in a sample mean of 60. The population standard deviation is o = 10 (a) Compute the 95% confidence interval for the population mean (Round your answers to two decimal places) to (0) Assume that the same sample mean was obtained from a sample of 160 items. Provide a 95% confidence interval for the population mean (Round your answers to two decimal places.) to (c) What is the effect of a targer sample size on the interval estimate? A larger sample sire provides a larger margin of error, A targer sample sise provides a smaller margin of error. A larger sample size does not change the margin of error Need Help
