Question

the most appropriate measure of center for this data is the median. complete which statement about the data is true? the mean is greater than the median. the mean is equal to the median. the mean is less than the median. complete what is the median of the data? retry weight of male dogs (lb.) 4 | 5 5 | 0 2 8 6 | 2 8 7 | 2 8 8 | 1 9 | 5 8|1 means 81

Explanation:

Step1: List all data values

From the stem-and-leaf plot, the data is: 45, 50, 52, 58, 62, 68, 72, 78, 81, 95

Step2: Order data (already ordered)

Count of data points: $n=10$ (even number)

Step3: Find median positions

For even $n$, median = average of $\frac{n}{2}$th and $(\frac{n}{2}+1)$th values.
$\frac{n}{2} = \frac{10}{2}=5$, $\frac{n}{2}+1=6$

Step4: Calculate median

5th value = 62, 6th value = 68
Median = $\frac{62 + 68}{2}$

Answer:

65
