Question 1

Find the indicated complement. A certain group of women has a 0.33% rate of red/green color blindness. If a woman is randomly selected, what is the probability that she does not have red/green color blindness? What is the probability that the woman selected does not have red/green color blindness? (Type an integer or a decimal. Do not round.)K 40% of consumers believe that cash will be obsolete in the next 20 years. Assume that 8 consumers are randomly selected. Find the probability that fewer than 3 of the selected consumers believe that cash will be obsolete in the next 20 years The probability is (Round to three decimal places as needed.) 10Assume that when human resource managers are randomly selected, 52% say job applicants should follow up within two weeks. If 7 human resource managers are randomly selected, find the probability that at least 4 of them say job applicants should follow up within two weeks. The probability is (Round to four decimal places as needed.)test In a survey, cell phone users were asked which ear they use to hear their cell phone, and the table is based on their responses. Determine whether a probability 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. P(x) Left 0.6359 Right 0.3043 No preference 0.0598 Does the table show a probability distribution? Select all that apply A. Yes, the table shows a probability distribution. B. No, the numerical values of the random variable x are not associated with probabilities.C. No, the sum of all the probabilities is not equal to 1. D. No, the random variable x is categorical instead of numerical. E. No, not every probability is between 0 and 1 inclusive. Find the mean of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. H= (Round to one decimal place as needed.) O B. The table does not show a probability distribution. Find the standard deviation of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. 6= /Dnund to ann dor larn or nondad )In a study of helicopter usage and patient survival, among the 58,631 patients transported by helicopter, 262 of them left the treatment center against medical advice, and the other 58,369 did not leave against K medical advice. If 50 of the subjects transported by helicopter are randomly selected without replacement, what is the probability that none of them left the treatment center against medical advice? The probability is (Round to three decimal places as needed.)Use the data in the following table, which lists survey results from high school drivers at least 16 years of age, Assume that subjects are randomly selected from those included in the table. Drove When Drinking Alcohol? Yes No Texted While Driving 699 3109 No Texting While Driving 164 4380 If one of the high school drivers is randomly selected, find the probability that the selected driver texted while driving and drove when drinking alcohol. The probability that one randomly selected high school driver texted while driving and drove when drinking alcohol is (Round to three decimal places as needed.)When a man observed a sobriety checkpoint conducted by a police department, he saw 687 drivers were screened and 9 were arrested for driving while intoxicated. Based on those results, we can estimate that P(W) =0.01310, where W denotes the event of screening a driver and getting someone who is intoxicated. What does P (W) denote, and what is its value? What does P (W) represent? O A. P (W) denotes the probability of a driver passing through the sobriety checkpoint. O B. P (W) denotes the probability of driver being intoxicated. O C. P (W) denotes the probability of screening a driver and finding that he or she is not intoxicated. O D. P (W) denotes the probability of screening a driver and finding that he or she is intoxicated. P (W) =] (Round to five decimal places as needed.)etermine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. he YSORT method of sex selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 50 couples use the YSORT method and give birth to 50 abies, the sex of the babies is recorded. Does the procedure represent a binomial distribution? O A. No, because the trials of the procedure are not independent. O B. Yes, because the procedure satisfies all the criteria for a binomial distribution O C. No, because there are more than two categories for each trial. OD. No, because the probability of success differs from trial to trial.Six of the 100 digital video recorders (DVRs) in an inventory are known to be defective. What is the probability that a randomly selected item is defective? The probability is (Type an integer or a decimal. Do not round.)K Men have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child. Complete parts a through d below. a. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a son will inherit the disease? Type an integer or a decimal. Do not round.) b. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a daughter will inherit the disease? Type an integer or a decimal. Do not round.) c. If a mother has one defective x chromosome and one good X chromosome and the father has good XY chromosomes, what is the probability that a son will inherit the disease? (Type an integer or a decimal. Do not round.) d. If a mother has one defective x chromosome and one good X chromosome and the father has good XY chromosomes, what is the probability that a daughter will inherit the disease? Type an integer or a decimal. Do not round.)K On their first date, Kelly asks Mike to guess the date of her birth, not including the year. Complete parts a through c below. a. What is the probability that Mike will guess correctly? (Ignore leap years.) (Type an integer or a simplified fraction.) b. Would it be unlikely for him to guess correctly on his first try? O A. No, it is not unlikely for Mike to guess correctly on his first try, as the probability of a correct guess is very high. O B. It is impossible for Mike to not guess correctly on his first try, as the probability of a correct guess is 1 O C. It is impossible for Mike to guess correctly on his first try, as the probability of a correct guess is 0. O D. Yes, it is unlikely for Mike to guess correctly on his first try, as the probability of a correct guess is very high. O E. Yes, it is unlikely for Mike to guess correctly on his first try, as the probability of a correct guess is very low. O F. No, it is not unlikely for Mike to guess correctly on his first try, as the probability of a correct guess is very low. c. If you were Kelly, and Mike did guess correctly on his first try, would you believe his claim that he made a lucky guess, or would you be convinced that he already knew when you were born? Mike as the probability of a correct guess is already knew, could have made a lucky guess, Next
