The weights of a certain dog breed are approximately normally distributed with a mean of μ = 52 pounds, and a standard deviation of σ = 6 pounds. A dog of this breed weighs 47 pounds. What is the dog's z-score? Round your answer to the nearest hundredth as needed. z = A dog has a z-score of -1.15. What is the dog's weight? Round your answer to the nearest tenth as needed. pounds A dog has a z-score of 1.15. What is the dog's weight? Round your answer to the nearest tenth as needed. pounds

Step 1
The z-score is calculated by subtracting the mean from the observed value and then dividing by the standard deviation. So, for a dog that weighs 47 pounds, the z-score would be (47 - 52) / 6 = -0.83. Show more…
