Identifying Probability Distributions. In Exercises 7-14, determine whether a prob- ability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied. 7. Genetic Disorder Five males with an X-linked genetic disorder X P(x) have one child each. The random variable x is the number of children 0.031 among the five who inherit the X-linked genetic disorder. 0. 156 N - 0.313 3 0.313 0.156 0.031 8. Male Color Blindness When conducting research on color P(x) blindness in males, a researcher forms random groups with five males in each group. The random variable x is the number of males 0.659 in the group who have a form of color blindness (based on data from 0.287 the National Institutes of Health). 0.050 U A W NO 0.004 0.001 0+ 9. Genetics Experiment A genetics experiment involves off- spring peas in groups of four. A researcher reports that for one P(x) O X group, the number of peas with white flowers has a probability dis- 0.04 tribution as given in the accompanying table. 0.26 0.36 0.20 0.08 10. Mortality Study For a group of four men, the probability dis- tribution for the number x who live through the next year is as given X P(x) in the accompanying table. 0.0000 1 0.0001 0.0006 0.0387 A 0.9606
