A study was conducted to determine the mean birth weight of a certain breed of kittens. Consider the birth weights of kittens to
be normally distributed. A sample of 45 kittens was randomly selected from all kittens of this breed at a large veterinary hospital. The birth weight of each kitten in the sample was recorded. The sample mean was 3.56 ounces, and the sample standard deviation was 0.2 ounces. Set a 90% confidence interval on the mean birth weight of all kittens of this breed
The altitude of the triangle intercepts perpendicularly meaning that the angle EHG equals to 90 degrees so.... 12x + 30 = 90 subtract 30 from both sides 12x = 60 divide both sides by 12 x = 5
