The shed is filled with sawdust whose density (kg/m3) at any point is proportional to the distance of that point from the floor. write a formula for the density, d, as a function of x, the distance from the floor in meters. use lower case k as the proportionality constant.

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?
