Answer :
The removal of the kitten with a mass of 57 kg will affect both the mean and median of the kitten masses.
Mean and median
Before removal, the mean is calculated by summing up all the masses and dividing by the total number of kittens. So:
(147 + 157 + 159 + 57) / 4 = 132 kg
After removal, if the kitten with a mass of 57 kg is removed, the sum of the remaining masses becomes:
(147 + 157 + 159) = 463 kg. Dividing by 3, the new mean becomes 154.33 kg.
The mean increases after the removal of the 57 kg kitten.
Before removal, the median is the middle value when the masses are arranged in ascending order. In this case, the middle values are 147 and 157 kg. So, the median is (147 + 157) / 2 = 152 kg.
After removal, if the 57 kg kitten is removed, the remaining masses are 147, 157, and 159 kg. The median remains the same at 157 kg.
The median remains unchanged after the removal of the 57 kg kitten.
In summary, the removal of the kitten with a mass of 57 kg increases the mean but does not affect the median of the kitten masses.

Answer:
Both the mean and median will decrease, but the mean will decrease by more than the median.

The more spread between grams means less mean and median but the mean will becrease more due to there being more variability
