A study examined whether the content of TV shows influenced the ability of viewers to recall brand names of items featured in the commercials. The researchers randomly assigned volunteers to
watch one of three programs, each containing the same nine commercials. After the shows ended, the subjects were asked to recall the brands of products that were advertised. A 95% confidence
interval for the difference in mean number of brands recalled between the violent and neutral programs (violent-neutral) was (-1.6,0.8). Based on the confidence interval, which of the following is
not possible?
Choose the correct answer below.
OA. The average number of brands recalled was the same for those watching neutral programming and those watching violent programming.
OB. Those watching neutral programming recalled 1 more brand than those watching violent programming, on average.
OC. Those watching neutral programming recalled 1 less brand than those watching violent programming, on average.
OD. Those watching neutral programming recalled 0.5 more brands than those watching violent programming, on average.
OE. Those watching neutral programming recalled 0.5 less brands than those watching violent programming, on average.
