When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 941 peas, with 735 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3/4 probability that a pea will have a red flower, we would expect that 705.75 (or about 706) of the peas would have red flowers, so the result of 735 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 735 or more peas with red flowers. b. Is 735 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/4 f peas will have red flowers? ---.- a. If the scientist's assumed probability is correct, the probability of getting 735 or more peas with red flowers is (Round to four decimal places as needed.) b. Is 735 peas with red flowers significantly high? v because the probability of this event is v than the probability cutoff that…
A blood bank asserts that a person with type O blood and a negative Rh factor (Rh−) can donate blood to any person with any blood type. Their data show that 49% of people have type O blood and 17% of people have Rh− factor; 52% of people have type O or Rh− factor. A. Find the probability that a person has both type O blood and the Rh− factor. B. Find the probability that a person does NOT have both type O blood and the Rh− factor.
The proportions of blood phenotypes A, B, AB, and O in the population of all Caucasians in the United States are reported as .40, .11, .04, and .45, respectively.¹ If a single Caucasian is chosen randomly from the population, what is the probability that he or she will have either type A or type AB blood?
Flying over the western states with mountainous terrain in a small aircraft is 40% riskier than flying over similar distances in flatter portions of the nation, according to a General Accounting Office study completed in response to a congressional request. The accident rate for small aircraft in the 11 mountainous western states is 2.5 accidents per 100,000 flight operations. (b) Find the probability of no accidents in 100,000 flight operations. (Use 4 decimal places.)(c) Find the probability of at least 8 accidents in 200,000 flight operations. (Use 4 decimal places.)
In a survey of U.S. adults with a sample size of 2082, 370 said Franklin Roosevelt was the best president since World War II. Two U.S. adults are selected at random from this sample without replacement. Complete parts (a) through (d). (a) Find the probability that both adults say Franklin Roosevelt was the best president since World War II. The probability that both adults say Franklin Roosevelt was the best president since World War II is O. (Round to three decimal places as needed.) (b) Find the probability that neither adult says Franklin Roosevelt was the best president since World War II. The probability that neither adult says Franklin Roosevelt was the best president since World War II is (Round to three decimal places as needed.) (c) Find the probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II. The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War II is.…
When a scientist conducted a genetics experiments with peas, one sample of offspring consisted of 927 peas, with 723 of them having red flowers. If we assume, as the scientist did, that under these circumstances, there is a 3/4 probability that a pea will have a red flower, we would expect that 695.25 (or about 695) of the peas would have red flowers, so the result of 723 peas with red flowers is more than expected. a. If the scientist's assumed probability is correct, find the probability of getting 723 or more peas with red flowers. b. Is 723 peas with red flowers significantly high? c. What do these results suggest about the scientist's assumption that 3/4 of peas will have red flowers?
Deer ticks can carry both Lyme disease and human granulocytic ehrlichiosis (HGE). In a study of ticks in the Midwest, it was found that 15 % carried Lyme disease, while 11 % carried HGE. In addition, of the ticks with either Lyme disease or HGE, 16 % carried both diseases. (a) What is the probability P[L H] that a tick carrries both Lyme disease (L) and HGE (H)? P[LH] = (b) What is the conditional probability that a tick carries HGE, given that it has Lyme disease? P[H|L] =
34% of a certain breed of rabbits are born with long hair. What is the probability that in a litter of 11 rabbits, exactly 6 will have long hair? (Give your answer correct to three decimal places.)
Suppose that a recent poll found that 50% of adults in a certain country believe that the overall state of moral values is poor. If a survey of a random sample of 15 adults in this country is conducted in which they are asked to disclose their feelings on the overall state of moral values, complete parts (a) through (e) below. Click here to view the table for the binomial probability distribution. Click here to view the table for the cumulative binomial probability distribution. (a) Find and interpret the probability that exactly 9 of those surveyed feel the state of morals is poor. The probability that exactly 9 of those surveyed feel the state of morals is poor is (Round to four decimal places as needed.) Interpret the results. Choose the correct answer below. In 100 trials of this experiment, we expect about to result in exactly 9 adults who feel the state of morals is poor. (b) Find and interpret the probability that no more than 4 of those surveyed feel the state of morals is…
