Which function can be used to model the monthly profit for x trinkets produced? f(x) = β4(x β 50)(x β 250) f(x) = (x β 50)(x β 250) f(x) = 28(x + 50)(x + 250) f(x) = (x + 50)(x + 250)
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?
