<u>Q3</u>
The data plotted against the frequency in an ogive is cumulative frequency.
<u>Q4</u>
A score of 50 under the column > c.f. with the boundaries 23.5 - 28.5 means 50 students got a score greater than 23.5.
<u>Q5</u>
Mean = 2(2) + 3 + 4 + 7(3) + 10 + 11 + 2(12) / 11
Mean = 4 + 7 + 21 + 21 + 24 / 11
Mean = 77/11
The mean is 7
<u>Q6</u>
The median is the middle term.
The median of the distribution is 7
Triangle WXZ and triangle XZY are similar triangles by the side angle side similarity postulate, therefore 16/12 = 12/9.
