Use the following information to answer the next four problems: In an experiment, 1919 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making 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. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 105 seconds with a standard deviation of 195 seconds. State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy.

Use the following information to answer the next four problems:

In an experiment, 1919 babies were asked to watch a climber attempt to ascend a hill. On two occasions, the baby witnesses the climber fail to make the climb. Then, the baby witnesses either a helper toy push the climber up the hill, or a hinderer toy preventing the climber from making 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. The amount of time the baby watched the event was recorded. The mean difference in time spent watching the climber approach the hinderer toy versus watching the climber approach the helper toy was 105 seconds with a standard deviation of 195 seconds.

State the null and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let μd=μhinderer−μhelper, where μhinderer is the population mean time babies spend watching the climber approach the hinderer toy and μhelper is the population mean time babies spend watching the climber approach the helper toy.
