Select the system of linear inequalities whose solution is graphed.

y > 3x – 1; x + 3y < 6

y ≥ 3x – 1; x + 3y ≤ 6

y < 3x – 1; x + 3y > 6

y ≤ 3x – 1; x + 3y ≥ 6

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?
