To estimate how many minutes a person who spends 20 minutes driving will spend listening to music based on the scatterplot data and trend line, we can look for the trend in the data points presented in the graph.
The data points listed indicate a general trend of increasing listening time with increasing driving time, but it might not be linear. Given the trend from the provided points, we can expect that as driving time approaches 20 minutes, the listening time will also increase.
Since the last data point mentioned is (17, 16), we can infer that at 20 minutes of driving, the listening time is likely to be just above 16 minutes, but not as high as 25 minutes.
Among the options given, the best inference seems to be around 18 minutes, as it fits the trend without significantly overshooting the previously observed data.
Therefore, the best inference is:
18 minutes.
