carsons tablet has 2000 videos. the play time for the videos is skewed to the right, with a mean of 135 seconds and a standard deviation of 25 seconds. Part 1: Can you accurately calculate the probability that the mean play time is more than 142 seconds for an SRS of 10 videos? Explain. Part 2: If you take a random sample of 50 videos instead of 10, explain how the Central Limit Theorem allows you to find the probability that the mean play time is more than 142 seconds. Calculate this probability and show your work.
