Hello, I need assistance with answers on these questions.

1.)

A population has mean p. =29 and standard deviaon (I: 5. Round me answers to two decimal places as needed. [a] Find the zscore for a population value of 14. The zseorefor a population value of 14 is E]. Get an education: A survey asked 32,109 people how much confidence they had in educational institutions. The results were as follows. Round your answers to four decimal places if necessary. Response Number A great deal 10,029 Some 17.866 Hardly any 4214 Total 32,109 Send data to Excel Part: 0 / 3 Part 1 of 3 (a) What is the probability that a sampled person has either a great deal or some confidence in educational institutions? The probability that a sampled person has either a great deal or some confidence in educational institutions isLet A and B be events with P(A) = 0.4, P(B) =0.6, and P(A or B) =0.7. (a) Compute P (A and B). (b) Are A and B mutually exclusive? Explain. (c) Are A and B independent? Explain. Part: 0 / 3 Part 1 of 3 (a) Compute P (A and B). P (A and B) = X 5Quality control: A population of 594 semiconductor wafers contains wafers from three lots. The wafers are categorized by lot and by whether they conform to a thickness specication, with the results shown in the following table. A wafer is chosen at random from the population. Write your answer as a fraction or a decimal, rounded to four decimal places. Lot Conforming Nonconforming A 88 12 B 156 43 C 254 41 II: Sen-d data in Excel :] (a) what is the probability that the wafer is from Lot C? (b) 1What is the probability that the wafer is nonconforming? (c) what is the probability that the wafer is from Lot C and is nonconforming? (cl) Given that the wafer is from Lot C, what is the probability that it is nonconforming? (e) Given that the wafer is nonconforming, what is the probability that it is from Lot C? (f) Let E] be the event that the wafer comes from Lot C, and let E2 be the event that the wafer is nonconforming. Are E1 and E2 independent? Part: 016 Part 1 of 6 The probability that the wafer is from Lot C is D. Determine whether the random variable A has a binomial distribution. If it does, state the number of trials n. If it does not, explain why not. A coin is flipped until a Head appears. Let A be the number of Heads. Part 1 of 2 X The random variable has a binomial distribution. . Your answer is incorrect. Correct Answer: The random variable does not have a binomial distribution. Part: 1 / 2 Part 2 of 2 Choose a statement that explains why \\ does not have a binomial distribution. O The number of trials is not fixed. O There are more than two possible outcomes for each trial. O The probability of success is not the same for each trial. O The trials are not independent. O X does not represent the number of successes that occur.A binomial experiment has the given number of trials :1 and me given success probability p. n=l,p={}.2 (3] Determine the probability 13(2). Round the answer to at least four decimal places. 19(2): E] High blood pressure: A national survey reported that 34% of adults in a certain county have hypertension {high blood pressure]. A sample of 24 adults is studied. Round the answer to at least four decimal places. (a) 1What is the probability that exacdy 5 of them have hypertension? The probability that exactly 5 of them have hypertension is D . (b) What is die probability that more than 7 have hypertension? The probability that more than T have hypertension is D . (c) what is the probability that fewer than 3 have hypertension? The probability that fewer than 3 have hypertension is D . ({1} Would it be unusual if more than 9 of them have hypertension? It (Choose one) 1' be unusual if more than 9 of them have hypertension since the _ probability is E]. The following table provides information about the top-grossing movies for the years 2009-2012.
