Previous research has shown that for young people, excessive screen time (that is, time spent in front of a TV or watching digital devices) is associated with lower mental wellbeing (among other health outcomes). With the increasing use of digital technology in the classroom and for homework, exposure to digital devices is hard to avoid, even for very young children. In a national survey, households were contacted by mail at random to identify those with children aged 14 years or less. The sampling frame was created from a census administrative register of household addresses. Households with children aged 14 or under who were willing to participate in the survey then completed a form listing the age and sex of all children aged 14 and under in the household. Within each household, one child aged 14 or under was then randomly selected by the survey administrators to be the subject of the survey. The variable SCREENTIME records how many hours on a weekday the child spends in front of the TV or on a digital device. The survey responses for 5 year old children are summarised in the frequency table below. SCREENTIME Frequency < 1 hour 264 1 hour 441 2 hours 481 3 hours 216 4 hours 128 5 hours 10

Here is an extract from an article discussing the effect of screen time on adolescent wellbeing."While use of digital technology did have a small negative association with well-being, it is important to put this association into context. In the full data set, smoking marijuana and being bullied were more closely linked with decreased well-being than using technology, while getting enough sleep and having regular meals were more closely linked with increased well-being."Which of the three estimation thinking questions is this trying to address?

The amount of television viewed by today's 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 watches television. The mean and the standard deviation for their responses were 12 and 2, respectively. PAWT constructed a stem-and-leaf display for the data that showed that the distribution of times was a symmetric, mound-shaped distribution. Give an interval where you believe approximately 95% of the television viewing times fell in the distribution.Group of answer choicesless than 16less than 10 and more than 14 hours per weekbetween 8 and 16 hours per weekbetween 6 and 18 hours per week
