3. Assume that 17% of the population is left-handed. A class of 188 students can be treated as a random sample. A professor needs to know the NUMBER of left-handed students for assigning seats for an exam. a. List the givens with the correct symbols: = 17% = 188 b. Fill in the wording for rv X = c. Compute the mean and standard deviation of the random variable in part b. correct symbol labeled answer with 2 decimal places correct symbol labeled answer with 2 decimal places d. What is the probability of the class having exactly 27 left-handed students? probability statement expression typed on the calculator numeric result (4 decimal places e. The room has 35 left-handed desks. What is the probability of running out of left-handed desks? probability statement expression typed on the calculator numeric result (4 decimal places f. Would 17 left-handed students be an unusually low number of left-handed students in a group of 188? Compute the correct probability to determine if 17 is an unusually low number of left-hander probability statement expression typed on the calculator numeric result (4 decimal places What would you conclude about the POPULATION PARAMETER if the class had 17 left-handers? Since , there (is/is not) significant evidence to conclude g. After the exam, the professor summarized his classroom data for the department office, and gave them the PERCENT of left-handed students he had out of 188, for future reference. He found that 23% of his class was left-handed. Is this an unusually high percent of left-handers? 1. Fill in the wording for rv p = 2. Compute the mean and standard deviation of the random variable in part 1. correct symbol answer with 2 decimal places correct symbol answer in EXACT form3. What is the probability of getting a sample of 188 with at least 23% left-handed? probability statement expression typed on the calculator numeric result (4 decimal places) What would you conclude about the POPULATION PARAMETER if the class had 23% left- handers? Since , there (is/is not) significant evidence to conclude
