A rectangular corral needs to be built using 200 feet of fencing. The function for the corral area is shown below, where A(w) is the area in square feet and w
is the width of the rectangle in feet. Find the maximum possible area of the
corral.
A(w) = 100w - W2

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?
