A nursery records the weights of 6 newborn babies in pounds. The weights are
6.7; 7.1; 7.5; 7.7; 8.1; 8.1; 8.3; 9.0.
Then twins are born. The weighed 8.1 and the girl weighed 7.1 pounds. What is the median weight in pounds of the eight babies born?
P.S. The twin weight are already in the numbers above.
6.7; 7.1;7.1 ; 7.5; 7.7; ....... 8.1;8.1; 8.1; 8.3; 9.0.
Median= 1/2 (8.1+7.7)=7.9
To find the median weight of the eight babies born, you need to arrange the weights in ascending order and then determine the middle value. Here are the steps to follow:
1. List all the weights: 6.7; 7.1; 7.5; 7.7; 8.1; 8.1; 8.3; 9.0.
2. Arrange the weights in ascending order: 6.7; 7.1; 7.5; 7.7; 8.1; 8.1; 8.3; 9.0.
3. The median is the middle value. Since there are an even number of weights (8), there are two middle values. In this case, the two middle weights are 7.7 and 8.1.
4. To find the median, take the average of the two middle values: (7.7 + 8.1) / 2 = 15.8 / 2 = 7.9.
Therefore, the median weight in pounds of the eight babies born is 7.9 pounds.
