A newspaper reported that the mean annual household income of its readers is GHC119,155. Assume this estimate of the mean annual household income is based on a sample of 80 households, and based on past studies, the population standard deviation is known to be o = GHC30,000. Develop a 95% confidence interval estimate of the population mean.
