. Approximately 10% of all people are left-handed, then the rest of people are right-handed. Consider a group of 15 people, answer the following question: (You cannot use the binomial table for this problem) (a) State the random variable ?. (2 points) (b) Explain why this is a binomial experiment. There should be 4 conditions to check. (State the probability of left-handed people ?, the possible outcomes, and the number of trials ? in the conditions.) (4 points) (c) Find the probability that exactly three people are left-handed. (Round your answer to 4 decimal places) (6 points) (d) Find the probability that at least two people are left-handed. (Round your answer to 4 decimal places) (8 points)

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,...

Approximately 13% of the population are left-handed. If three people are randomly selected, what is the probability that all are left- handed? (round to 4 decimal places) If three people are randomly selected, what is the probability that at least 1 person is not left handed? (round to 4 decimal places) Notice that these two events are complementary (the probabilities do add up to 1).

It has been claimed that, on average, right-handed people have a left foot that is larger than the right foot. Here we test this claim on a sample of 10 right-handed adults. The table below gives the left and right foot measurements in millimeters (mm). Test the claim at the 0.05 significance level. You may assume the sample of differences comes from a normally distributed population. Person Left Foot (x) Right Foot (y) 1 268 268 2 265 263 3...
