Final answer:
The mean height is 150.2 cm, the median is 150 cm, and the mode is 145 cm.
Explanation:
To find the mean (or average) of the heights, you sum up all the values and then divide by the number of values. In this case,
[tex]\( \text{Mean} = \frac{155 + 161 + 145 + 149 + 150 + 145 + 152 + 145 + 140}{9} = \frac{1352}{9} = 150.2 \) cm[/tex]
For the median, which is the middle value when the data is arranged in ascending or descending order, you first order the data: 140, 145, 145, 145, 149, 150, 152, 155, 161. Since there are 9 values (an odd number), the median is the fifth value, which is 150 cm.
To determine the mode, which is the value that appears most frequently, you can see from the ordered list that the height 145 cm appears three times, more than any other value. Thus, the mode is 145 cm.

Answer:
Mean is 149.1
Median is 149
Mode 145
Step-by-step explanation:
to get the mean, add all the numbers and divide by 9
To get the median, arrange the number from smallest to the biggest, the number in the middle is the median
To find the mode, just look at the number that appears often
