The mean height for the five dogs is 405mm. To calculate the mean, the heights of all the dogs are added together and then divided by the number of dogs. In this case, the heights of the five dogs are 300mm, 430mm, 170mm, 470mm, and 600mm, for a total of 2,270mm. When this total is divided by 5 (the number of dogs), the mean height is calculated to be 405mm.
