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.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
