The amount of television viewed by today's youth is of primary concern to a certain organization. Three hundred 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 2, respectively. The organization 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
most (approximately 95%) of the television viewing times fell in the distribution.
OA. between 14 and 18 hours per week
B. between 10 and 22 hours per week
OC. less than 14 and more than 18 hours per week
D. between 12 and 20 hours per week
