One of the questions in the Pew Internet & American Life Project asked adults if they used the Internet, at least occasionally (Pew website, October 23, 2012). The results showed that 454 out of 478 adults aged 18, 29 answered yes; 741 out of 833 adults aged 30, 49 answered yes; and 1058 out of 1644 adults aged 50 and over answered yes.

a. Develop a point estimate of the proportion of adults aged 18, 29 whouse the Internet.

b. Develop a point estimate of the proportion of adults aged 30, 49 whouse the Internet.
c. Suppose your target population of interest is that of all adults (18 yearsof age and over). Develop an estimate of the proportion of that population who use the Internet.

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.
