10 points 7. The two circles have different radii and the arcs highlighted in blue are
different lengths. Are the angles marked alpha and beta (the two Greek
letters) also different in measure?
L = 8
( = 4
a
Ar=6
R= 12
O no
O yes, alpha is 2 times bigger than beta
yes, alpha is 2 times smaller than beta
yes, but it's impossible to tell how much different they are

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?
