A random sample of 750 registered voters in Phoenix is asked if they favor the use of oxygenated fuelsyear-round to reduce air pollution. If more than 315 voters respond positively, we will conclude that atleast 40% of the voters favor the use of these fuels.Question-1Formulate the null and alternative hypothesisQuestion-2Find the probability of type I error if exactly 40% of the voters favor the use of these fuels.Question-3What is the type II error probability B if 38% of the voters favor this action?Question-4Would increasing the sample size decrease the probability of rejecting the proportion that 40% are infavor of the use of oxygenated fuelsv Question-1a.

In a recent survey, 70% of management executives thought that it should be mandatory for business students to take a course in Quantitative methods. Fora random sample of 5 human resource directors, what is the probability that at least two of them think that it should not be mandatory for business students to take a quantitative methods course?
A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 90.2% for the medical students admitted through special programs. Be sure to enter at least 4 digits of accuracy for this problem! If 9 of the students from the special programs are randomly selected, find the probability that at most 6 of them graduated.P(at most 6) = At least 4 digits! Would it be unusual to randomly select 9 students from the special programs and get at most 6 that graduate? no, it is not unusual yes, it is unusual Would it be unusual to randomly select 9 students from the special programs and get only 6 that graduate? no, it is not unusual yes, it is unusual
A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 41 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If one shipment of 4000 aspirin tablets actually has a 4% rate of defects, what is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will be accepted is 0.5080'. (Round to four decimal places as needed.) The company will accept % of the shipments and will reject % of the shipments, so (Round to two decimal places as needed.)

A diagnostic test for disease X correctly identifies the disease 88% of the time. False positives occur 11%. It is estimated that 2.78% of the population suffers from disease X. Suppose the test is applied to a random individual from the population. Compute the following probabilities. The percentage chance that, given a negative result, the person does not have disease X= The percentage chance that, the person will be misclassified =
A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 52 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If one shipment of 4000 aspirin tablets actually has a 5% rate of defects, what is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will be accepted is ______ (Round to four decimal places as needed.) The company will accept ____% of the shipments and will reject ____% of the shipments, so______________ (many of the shipments will be rejected or almost all of the shipments will be accepted.

A study was performed to assess the feasibility of a national random digit dialing cellular phone survey among young adults age 18-34. It was reported that 3.2% of respondents were eligible to participate and that 55% of eligible respondents agreed to participate. Suppose 1000 potential participants are contacted to participate in this survey. What is the approximate probability that at least 12 of the 1000 participants will be eligible and agree to participate?
