(b) Suppose you wanted to use the sample data to decide if there is evidence that the average time spent playing video or computer games for male Canadian high school students i greater than 2 hours (120 minutes). What would you need to know to determine if the one-sample t test is an appropriate method? (Select all that apply.) We would need to know that the distribution of the population of times is approximately normal or that the sample size is large. O We would need to know that all observations are dependent or all observations are independent. We would need to know that the sample was randomly selected or is representative of the population of male Canadian high school students. We would need to know that all male Canadian high school students were surveyed or the sample is representative of the population of male Canadian high school students. We would need to know that the distribution of the population of times is approximately normal or that the sample size is small.
