Check My Work (2 remaining) A simple random sample of 10 items resulted in a sample mean of 30. The population standard deviation is o = 15. a. Compute the 95% confidence interval for the population mean, Round your answers to one decimal place. b. Assume that the same sample mean was obtained from a sample of 110 items. Provide a 95% confidence interval for the population mean Round your answers to two decimal places. c. What is the effect of a larger sample size on the interval estimate? Larger sample provides a Select your answer - margin of error. Check My Work (2 remaining) A simple random sample of 10 items resulted in a sample mean of 30.
