A graduate student conducted an experiment in which 18 ten-month-old babies were asked to watch a climber character attempt to ascend a hill. On two occasions, the baby witnesses the character fail to make the climb. On the third attempt, the baby witnesses either a helper toy push the character up the hill or a hinderer toy prevent the character from making the ascent. The helper and hinderer toys were shown to each baby in a random fashion for a fixed amount of time. The baby was then placed in front of each toy and allowed to choose which toy he or she wished to play with. In 15 of the 18 cases, the baby chose the helper toy. Complete parts (a) through (d) below. than 0.5. (d) In testing 12 six-month-old babies, all 12 preferred the helper toy. The P-value was reported as 0.0002. Interpret this result. Choose the correct answer below. O A. If the population proportion of babies who choose the helper is 0.5, a sample where all 12 babies choose the helper will occur in about 2 out of 10,000 samples of 12 babies. O B. If the population proportion of babies who choose the helper is 0.5, a sample where all 12 babies choose the helper will occur in exactly 12 out of 1000 samples of 12 babies. C. If the population proportion of babies who choose the helper is 0.5, a sample where all 12 babies choose the helper will occur in about 12 out of 1000 samples of 12 babies. O D. If the population proportion of babies who choose the helper is 0.5, a sample where all 12 babies choose the helper will occur in exactly 2 out of 10,000 samples of 12 babies.
