Approximately 10% of people in the world are left-handed, so P(a person is left handed) = 0.1. Suppose we have a class of 15 people and UHD is interested in how many left-handed desks the class will need, so we define a random variable X, the number of left-handed people in the class. 1. What distribution family does this situation belong to? What is (are) the parameter(s)? 2. What is the probability that none of the students will be left...

3. The Jordan Sports Equipment Company finds that 10% of the general population is left-handed. Use the binomial table or formula (bottom) as appropriate in answering the following questions. (a) If 20 people are randomly selected, find the probability that exactly 3 of them are left-handed. (b) If 8 people are randomly selected, find the probability that at least one of them is left-handed.

Approximately 15% of the population is left-handed. Assume that a sample of 151 people is selected and the sample proportion p ^ of left-handed individuals is calculated. Find the probability that proportion of people in the sample who are left handed is within 4% of the true population proportion.

2. Suppose that 10% of the general population is left-handed (a) We randomly sample 20 individuals. Find the probability that fewer than 2 of them are left handed. Hint: You cannot use the normal distribution (b) we randomly sample 200 individuals. Find the probability that less than 8% of them are left handed.

Do left-handed people live shorter lives than right-handed people? A study of this question examined a sample of 949 death records and contacted next of kin to determine handedness. Note that there are many possible definitions of "left-handed." The researchers examined the effects of different definitions on the results of their analysis and found that their conclusions were not sensitive to the exact definition used. For the results presented here, people were defined to be right-handed if they wrote, drew,...
