Directions: Given the slope and y-intercept of the line, write the equation in slope-intercept form.
1.slope = 2; y-intercept = -1
3.slope = -3; y-intercept = 2
5.slope =1/4;y-intercept =0

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?
