To find the mean weight, add the weights of all the cats and divide by the number of cats: Mean weight = \(\frac{5 + 11 + 12 + 6 + 13}{5} = \frac{47}{5} = 9.4\) pounds. For the median, first, arrange the weights in ascending order: \(5, 6, 11, 12, 13\). Since there are 5 weights, the median is the middle weight, which is \(11\) pounds. So, the mean weight is **9.4 pounds** and the median weight is **11 pounds**.

2.2 Two Grade 11 Mathematics classes have the same number of learners. The five- number summaries of the marks obtained by these classes for a test are shown below. CLASS A \( (30 ; 48 ; 65 ; 82 ; 90) \) CLASS B \( (50 ; 58 ; 65 ; 75 ; 90) \) The parents of learners in CLASS A and CLASS B observe that both classes have the same median and the same maximum mark and therefore claim that there is no difference in the performance between these classes. Do you agree with this claim? Use at least Two different arguments to justify your answer. [13]
