Aprofessor states that in the united states the proportion of college students who own iphones is .66. she then splits the class into two groups: group 1 with students whose last name begins with a-k and group 2 with students whose last name begins with l-z. she then asks each group to count how many in that group own iphones and to calculate the group proportion of iphone ownership. for group 1 the proportion is p1 and for group 2 the proportion is p2. to calculate the proportion you take the number of iphone owners and divide by the total number of students in the group. you will get a number between 0 and 1.

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.
