Final answer:
Modal class for the distribution of time spent on the internet in the previous 24 hours is d) More than 241
Step-by-step explanation:
To identify the modal class for the distribution of time spent on the internet, we would need a frequency table showing how many students fall into each time category (00-60 minutes, 61-120 minutes, etc.).
The modal class is the class interval with the highest frequency. Without additional data, we cannot determine which option is correct.
For the traffic rate question, it is given that website traffic follows the exponential distribution with a rate of 12 visits per hour.
Using the exponential distribution formula P(X > x) = e-λx, we can calculate the requested probabilities.
the modal class for the distribution of time spent on the internet in the previous 24 hours is d) More than 241
