Liam works at a zoo. He was looking at some data showing the masses of their 555 African elephants. The mean mass of the elephants was 3{,}800\,{\text{kg}}3,800kg3, comma, 800, start text, k, g, end text, and the median mass was 3{,}600\,{\text{kg}}3,600kg3, comma, 600, start text, k, g, end text. The smallest elephant, named Lola, weighed 2{,}700\,{\text{kg}}2,700kg2, comma, 700, start text, k, g, end text. Lola then got very sick and lost weight until her mass reached 1{,}800\,{\text{kg}}1,800kg1, comma, 800, start text, k, g, end text. How will Lola's mass decreasing affect the mean and median? |

Answer» : 5 African elephantsThe mean mass of the elephants was 3800 kgThe median mass of the elephants was 3600 kgThe smallest ELEPHANT, named Lola, weighed 2700 kgLola then got very sick and lost weight until her mass reached 1800 kgTo Find : How will Lola's mass decreasing affect the mean and median?Solution:2700 , A , 3600 , B , C as Median is 3600 and lowest is 2700 now 2700 becomes 18001800 , A , 3600 , B , Cso Median REMAINS the same as 3600No change in MedianThe mean mass of the elephants was 3800 kg=> total weight = 5 x 3800 = 19000 kg2700 kg becomes 1800 kgHence new total mass = 19000 - 2700 + 1800= 181000 kgNew Mean = 18100/5 = 3620 kg Mean reduced by 3800 - 3620 = 180 kgNo change in Median weightMean reduced by 180 kgLearn More:for a given data 2,3,5,6,9 if OBSERVATION 6.9 are replaced by 4 and 11 ... brainly.in/question/8334923 If the first quartile is 142 and the semi-interquartile range is 18, find ... brainly.in/question/13279139 Nia recorded her science and math scores.
