∠A and \angle B∠B are complementary angles. If m\angle A=(6x-8)^{\circ}∠A=(6x−8) ∘ and m\angle B=(5x+21)^{\circ}∠B=(5x+21) ∘ , then find the measure of \angle B∠B. pls i need the answer rn

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?
