The amount of television viewed by todays youth is of primary concern to Parents Against Watching Television (PAWT).
300 parents of elementary school-aged children were asked to estimate the number of hours per week that their child watched television. The mean and the standard deviation for their responses were 16 and 4, respectively. PAWT constructed a stem-and-leaf display for the data that showed that the distribution of times was a bell-shaped distribution. Give an interval around the mean where you believe most (approximately 95) of the television viewing times fell in the distribution. A) between 8 and 24 hours per week B) less than 12 and more than 20 hours per week
C) between 4 and 28 hours per week D) between 12 and 20 hours per week
