Climatologists are monitoring the sea surface tempera- ture off the coast of Nigeria. When they average the
monthly temperatures in an attempt to predict the onset
of diseases such as cholera, malaria, and dengue fever,
they can add the daily temperatures in any order. What
mathematical property does this demonstrate?

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu . assume that the population has a normal distribution. a laboratory tested twelve chicken eggs and found that the mean amount of cholesterol was 185 milligrams with sequals 17.6 milligrams. a confidence interval of 173.8 mgless than muless than 196.2 mg is constructed for the true mean cholesterol content of all such eggs. it was assumed that the population has a normal distribution. what confidence level does this interval represent?
