A website streams movies and television shows to millions of users. Employees know that the average time a user spends per session on their website
is 2 hours. The website changed its design, and they wanted to know if the average session length was longer than 2 hours. They randomly
sampled 100100100 users and found that their session lengths had a mean of 2.75 hours and a standard deviation of 1.55 hours.
The employees want to use these sample data to conduct at test about the mean.
Which conditions for performing this type of test did their sample meet?
The data is a random sample from the population of interest
The sampling distribution of x-bar is approximately normal.
Individual observations can be considered independent.
