Show all assumptions, discussions, and calculation steps. Humans are predominantly right-handed. Do other animals exhibit handedness as well? Bisazza et al. (1996) tested the possibility of handedness in European toads, Bufo bufo, by sampling and measuring 18 toads from the wild. We will assume that this was a random sample. The toads were brought to the lab and subjected one at a time to the same indignity: a balloon was wrapped around each individual's head. The researchers then recorded which forelimb each toad used to remove the balloon. It was found that individual toads tended to use one forelimb more than the other. Use the provided table below to answer the question: \"Do right-handed and left-handed toads occur with egual freguency in the toad population, or is one page more freguent than the other, as in the human population?\" Here are some key points you need to Show before a convincing conclusion is drawn: 0 The parameter of interest is the proportion p of right-handed toads in the population. Based on this, provide the null hypothesis and the alternative hypothesis. l-sided or 2-sided hypothesis, why? The test statistics. The null distribution A plot of the data (so you can see some unusual numbers, e.g. to have 17 right-handed toads when 18 are sampled is very unusual 0.007% to observe). This will help you setup a threshold to decide either reject or accept your hypothesis. 0 The P-Value 0 Your decision (accept or reject the null hypothesis), why? 0 Your scientic conclusion (translate all previous statistical results into English, in a sentence or two. Here, you are nally answering the underlined question above.) Table: All possible outcomes for the number ofright-handed toads when 18 toads are sampled, and their probabilities under the null hypothesis.
