One consequence of the popularity of the internet is that it is thought to reduce television watching. suppose that a random sample of 4545 individuals who consider themselves to be avid internet users results in a mean time of 2.082.08 hours watching television on a weekday. determine the likelihood of obtaining a sample mean of 2.082.08 hours or less from a population whose mean is presumed to be 2.452.45 hours.

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41

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.

What’s the answer? and how do i solve it ?
