Answer 1

Use the properties of the mean and median to determine which are the correct mean and median for the following 0.30 0.25 0.20 Relative Frequency 0.15 0.10 0.05 0 3 6 & Choose the correct answer. Х $ Mean is 2.5 and median is 2.6. Mean is 4.2 and median is 3.5. Mean is 3.5 and median is 4.2. O Mean is 4.2 and median is 4.6. ор

Because

Given data Approximately normal and Left skewed

so mean is less than the median

Mean $\mu =\Sigma xP(x)=4.19\approx 4.2$
