7) What is the equation of the circle with center (−3, 1) that passes through the point (−5, 3)?
A)(x − 3)2 + (y + 1)2 = 8
B)(x + 3)2 + (y −1)2 = 8
C)(x + 1)2 − (y − 3)2 = 8
D)(x + 3)2 − (y − 1)2 = 8

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?
