If x and y represent the mean and the median respectively of the following set of numbers 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, find the \(\frac{x}{y}\) correct to one decimal place
- 18
- 15
-
1.0
- 5
The correct answer is: C
Explanation
Mean \(\bar{x}\) = \(\frac{156}{10}\) = 15.6Median = \(\bar{y}\) = \(\frac{15 + 16}{2}\)
\(\frac{31}{2}\) = 15.5
\(\frac{x}{y}\) = \(\frac{15.6}{15.5}\) = 1.0065
