In an experiment, 17 babies were asked to watch a dober attempt to ascend a hill On two ocomions, the baby witnesses the deber fall to make the deb. Then, the baby wies her a hopes to push the deep the ht, or a hinderer toy preventing the climber from making the and The toys were shown to each hatly in a random fashion A second part of this experiment showed the climber approach the helper toy, which is s action, and then the chamber approached the hinderer toy, which is a supeting action. The amou time the baby watched each event was recorded. The mean diference in time spent watching the climber approach the des try versan watching the climber approach the helper toy was 1.25 seconds with a standard deviation o seconds. Complete parts (a) through (c) below Click the icon to view the table of critical va (a) State the mall and alternative hypotheses to determine if babies tend to look at the hinderer toy longer than the helper toy. Let Paper where is the population mean time bates spond watching the climber appenach the hindrer toy and is the population mean time babies spend watching the climber approach the helper try 1 P H (b) Assuming the differences are normally dichibuted with no outlers, test if the diference in the amount of time a baby will watch the hinderer toy versus the helper koy is greater than 0 at the 0.01 level of signience Find the test statistic for this hypothesis (Round to two decimal places as needed) Approximate the P-value for this hypothesis test The P-value is in the range State the conchision for this hypothesis test
