experiment, 16 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fall to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the ing the ascent. The toys were shown to each baby in a random fashion. A second part of this experiment showed the climber approach the helper toy, which is not a surprising action, and then the climber approached the hinderer toy, which is a surprising action ount of time the baby watched the event was recorded. The mean difference in lime spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 1.13 seconds with a standard deviation of 1.72 seconds Comple rough c (a) State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let Hd hinderer Phelper where Phinderer is the population mean time babies spend watching the climber approach the hinderer loy and population mean time babies spend watching the climber approach the helper toy. 12 OA HA=0 H P 0 O E.
