The endpoints of a diameter of a circle are located at (5.9) and (11.17). Which is
an equation of the circle?
a) (r - 8)2 + (1 - 13)2 = 100
b) (1 - 5)2 + (y - 9)2 = 25
c) (x - 5)2 + (y - 9)2 = 100
d) ( -8) + (1 - 13)2 = 25

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?
