Final answer:
The correlation coefficient between age and Internet usage requires specific data on ages and Internet usage times, which was not provided. Therefore, without this data, we cannot calculate or choose the correct correlation coefficient from the options given.
Step-by-step explanation:
To find the correlation coefficient between age and Internet usage among people aged 15 to 24 years, we would need access to the raw data of the two variables (age and Internet usage) for each individual within the specified age range. This data would typically consist of two sets of values: one representing the ages of the individuals and the other representing their corresponding Internet usage times. Once the data is available, we could employ statistical methods to calculate the correlation coefficient, a value that quantifies the strength and direction of the relationship between the two variables. The calculation involves using formulas or statistical software to derive a value between -1 and 1, where 1 indicates a perfect positive correlation, -1 indicates a perfect negative correlation, and 0 indicates no correlation.
Since the provided information does not contain the necessary data, it is not possible to calculate or accurately select the correlation coefficient from the given options. If you provide the specific data points for the ages and the corresponding Internet usage times, I can guide you through the steps to calculate the correlation coefficient.
