This is a confusing question which polynomial is written in standard form x^3y^2+4x^4y+10x^9 or x^4y^2+4x^4y^5 + 10x^2 or xy^2+4x^3y^8+10x^2 or x^4y^5+4x^3y^2+10x^2

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?
