Q1.
Ms Renu divided her students into groups of 8 each and asked them to record their weights. She further asked the groups to calculate the mean weight of their respective group. Group A (which consists of 8 students) measured their weights and calculated the mean weights as 38.2 kg. Later on they realized that the weight of one of the student they recorded is incorrect. Instead of 25.9 kg, they recorded it as 29.5 kg. What will be the correct mean for the group?
