Correct answer is D
Mean = \(\frac{8 + 18 + 10 + 14 + 18 + 11 + 13 + 14 + 13 + 17 + 15 + 8 + 16 + 13}{14}\)
Mean = \(\frac{188}{14}{\)
Mean = 13.4
Number above the mean is 7
The following are scores obtained by some students in a test. Find the median score
| 8 | 18 | 10 | 14 | 18 | 11 | 13 |

Correct answer is A
No of fruits = x
\(\frac{80}{360}\) x \(x\) = 60
x = \(\frac{60 \times 360}{80}\) x 270
= 90
\(\frac{1}{6}\)
\(\frac{1}{4}\)
\(\frac{1}{3}\)
\(\frac{1}{2}\)
Correct answer is C
Pr(green) = \(\frac{6}{5 + 6 + 7}\)
= \(\frac{6}{18}\)
= \(\frac{1}{3}\)
