Layla is working on a PhD in computer science and wonders what the average page length is for dissertations in her field. She takes a random sample of 808080 computer science dissertations and notices that the distribution of their page lengths is skewed to the right with high outliers and a sample mean of \bar x=125.4 x ˉ =125.4x, with, \bar, on top, equals, 125, point, 4 pages. She's considering using her data to make a confidence interval for the mean page length of computer science dissertations. Which conditions for constructing a ttt interval have been met? Choose all answers that apply: Choose all answers that apply: (Choice A) A The data is a random sample from the population of interest. (Choice B) B The sampling distribution of \bar x x ˉ x, with, \bar, on top is approximately normal. (Choice C) C Individual observations can be considered independent.
