points) possible A psychologist is studying the sense of taste and smell by administering 20 different foods by dropping a liquid on the tongues of students. Based on her past research, the mean number of the 20 foods that students can identify correctly is 13, with a standard deviation of 3, and the distribution of scores follows a normal curve The psychologist wants to test whether people do worse on the task when they are only able to taste the liqud compared to when they can both taste and smell it (note that this is a directional hypothesis) The psychologist then tries the procedure on one randomly selected student when smell is not a factor This student is able to identity only 9 correctly. Complete parts (a) and (b) below (a) Using the 005 significance level, what should the psychologist concludo? First determine the full hypothesis. Choose the correct answer below O A. People do better on the task when they are only able to taste the liquid compared to when they can both taste and smell it. OB. People identity only 9 conectly when they are only able to taste the liquid and can identity 13 correctly when they can both taste and small t. Oc People do worse on the task when they are only able to taste the liquid compared to when they can both taste and smell it OD. People do the same, or better on the task when they are only able to taste the liquid compared to when they can both taste and smelt. Determine the research hypothesis. Choose the correct answer below. O A People do worse on the task when they are only able to taste the liquid compared to when they can both taste and smelit O B. People identity only 9 correctly when they are only able to taste the liquid and can identity 13 correctly when they can both taste and smell OC.
