The television show 50 minutes has been successful for many years. that show recently had a share of 29, meaning that among the tv sets in use, 29% were tuned to 50 minutes. assume that an advertiser wants to verify that 29% share value by conducting its own survey, and a pilot survey begins with 15 households have tv sets in use at the time of a 50 minutes broadcast.
find the probability that none of the households are tuned to 50 minutes. p(none) = (round answer to 4 decimal places)
find the probability that at least one household is tuned to 50 minutes. p(at least one) = (round answer to 4 decimal places)
find the probability that at most one household is tuned to 50 minutes. p(at most one) = (round answer to 4 decimal places)
if at most one household is tuned to 50 minutes, does it appear that the 19% share value is wrong? (hint: is the occurrence of at most one household tuned to 50 minutes unusual? )
a. yes, it is wrongb. no, it is not wrong

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.
