Final answer:
The mean weight of the students is calculated by adding all the weights together and dividing by the number of students. After summing up the weights of 49.94 kg, 46.94 kg, 50.69 kg, and 48.44 kg, and dividing by four, the mean weight is found to be 49.0025 kg.
Step-by-step explanation:
To find the mean weight of the given students' weights, you need to add up all the weights and then divide by the number of students. In this case, we have four students with the following weights: 49.94 kg, 46.94 kg, 50.69 kg, and 48.44 kg.
First, we add the weights together:
49.94 kg + 46.94 kg + 50.69 kg + 48.44 kg = 196.01 kg.
Then, we divide the total weight by the number of students, which is four:
196.01 kg ÷ 4 = 49.0025 kg.
Therefore, the mean weight of the students is 49.0025 kg.
