Final Answer:
The median of the data is 149, making the correct choice: a. 149.
Explanation:
The median of a dataset is the middle value when the data is arranged in ascending order.
Given the values 155, 160, 145, 149, 150, 147, 152, 144, and 148, arranging them in ascending order yields 144, 145, 147, 148, 149, 150, 152, 155, and 160. As there are 9 values (an odd number), the median corresponds to the middle value, which is 149.
This selection matches option a. 149, making it the correct answer. The median is a measure of central tendency that provides insight into the data's central value, unaffected by extreme values.
