In anexperiment, 15 babies were asked to watch a climber attempt to ascend a hill. On twooccasions, the baby witnesses the climber fail to make the climb.Then, the baby witnesses either a helper toy push the climber up thehill, 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 helpertoy, which is not a surprisingaction, and then the climber approached the hinderertoy, 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 1.16 seconds with a standard deviation of 1.53 seconds. Complete parts a through 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 d=hindererhelper, where hinderer is the population mean time babies spend watching the climber approach the hinderer toy and helper is the population mean time babies spend watching the climber approach the helper toy.

b)Assuming the differences are normally distributed with nooutliers, test if the difference in the amount of time the baby will watch the hinderer toy versus the helper toy is greater than 0 at the 0.10 level of significance.

Find the test statistic for this hypothesis test and then P Value

c) State the conclusion for this hypothesis test.

d) What do you think the results of this experiment imply aboutbabies' ability to assess surprisingbehavior?
