Evaluate 8j -k+148j−k+14 when j=0.25j=0.25 and k=1k=1.

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?

Rewrite the expression in z to the n power. the expression i was given is: 1 over z to the negative 1 half power.
