Which series of transformations results in the image being congruent to the pre-image? (x, y) → (2x, y) (x, y) → (x , y + 7) (x, y) → (–x, –y) (x, y) → (x – 5, y) (x, y) → (x, –y) (x, y) → (0.75x, 0.75y) (x, y) → (–x, y) (x, y) → (3x, 3y) (x, y) → (x – 9, y) (x, y) → (–x, –y) (x, y) → (x + 4, y) (x, y) → (x, y – 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?
