class A has 11 pupils and class B has 14 pupils. Both classes sit the same maths test. the mean score for class A is 32. The mean score for class B is 38. What is the mean score(rounded to 2DP) in the maths test across both classes?

35.36

Step-by-step explanation:

For Class A

Class A has 11 pupils

The mean score for Class A is 32.

The total score of the students =

Mean score × Number of pupils

= 32 × 11

= 352

For Class B

Class B has 14 pupils. The mean score for class B is 38.

The total score of the students =

Mean score × Number of pupils

= 38 × 14

= 532

Total number of pupils for both classes = (11 + 14)pupils

= 25 pupils

Total score for both class = 532 + 352

= 884

The mean score(rounded to 2DP) in the maths test across both classes is calculated as:

Total score of both classes÷ Total number of pupils

884 ÷ 25
