In one study, Zwerg, when given two choices, successfully chose the object pointed at by the experimenter 37 times out of 48 trials. Does this result show that Zwerg can correctly follow this type of direction ("pointing at") by an experimenter more than 50% of the time?
- Use an applet to generate the null distribution of sample proportion of correct answers and use it to determine the standardized statistic.
- Interpret the standardized statistic in the context of the study. (Hint:You need to talk about the value of your observed statistic in terms of standard deviations assuming ______ is true.)
- Based on the standardized statistic, state the conclusion that you would draw about the research question of whether Zwerg does better than randomly guess when the cue is that the experimenter points at the correct object.
