To test this idea, they recruit six- month-old children to watch a puppet show. In the show are three characters: A Kitty Cat that is trying to open a box to get a treat inside. A Bunny Rabit with a red sweater. And a second Bunny with a green sweater. The children then watch multiple trials of the Bunny in the green sweater help the Kitty get the treat out of the box. They also watch multiple trials of the Bunny in the red sweater slamming the box closed making it so that Kitty cannot get the treat. Later, the children are given a choice of which Bunny they want. Both Bunnies (one with a green sweater, the other with a red sweater) are offered to the child. This happens over multiple times and then a mean is calculated for each child about how often the reached for the Bunny with the green sweater (the "good" bunny). The researchers' reason that if the child reaches for the green sweater "good" Bunny more often than expected by chance, that suggests that even young children have a sense of right and wrong. . Below are the average percentages that children in the study reached for the bunny with the green sweater, the average (SD) across all subjects is also reported. 50 55 65 70 75 60 45 65 75 40 45 55 80 60 X = 60.00 SD = 12.91Below are the average percentages that children in the study reached for the bunny with the green sweater, the average (SD) across all subjects is also reported. 50 55 65 70 75 60 45 65 75 40 45 55 80 60 X = 60.00 SD = 12.91 Calculate a significance test to test whether the outcomes here are due to: Using an alpha level of .05, calculate a critical value: (Please enter to the second decimal place.)
