You are doing marketing research about yogurt consumption. Based on your previous research, you feel sure that the population standard deviation of the number of yogurts consumed per year is 6. In other words, is known and 6. You take a sample of 50 consumers and the sample mean is 32 yogurts consumed per year. In other words, x = 32. You want to develop a confidence interval for (the population mean) such that you are 90% confident that the...
