Katie is 44 years younger than Sylvia. ​Let kk represent Katie’s age, ​and let ss represent Sylvia’s age.​

Part A

Using the variables defined above, write an equation that ​shows the relationship between Katie’s age and Sylvia’s age.

Part B

Use the equation from Part A to find how old Sylvia is when ​Katie is 13 years old.

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?
