The election commission in a certain county has decided that before electronic voting machines can be placed in service, there must be strong evidence that the machines will correctly record more than 99% of the ballots cast. In testing the machines, a random sample of size 2500 of ballots recorded by the machine were checked against the paper ballots filled out by the inspectors, and it was found that 2483 had been recorded correctly. On the basis of these data, can the machines be placed in service?

When applying for insurance, potential cus- tomers are asked if they have good or bad credit. Just before approving the new cus- tomer, the insurance company orders a credit report to verify the customer's actual credit rating. Historically, 49% of customers with bad credit claim they have good credit and 12% of customers with good credit misreport they have bad credit. If the insurance com- pany has set its credit standards so that 51% of approved customers have good credit, what is the probability an approved customer has good credit, given that they claimed to have good credit during the application process? Round answer to the nearest whole percent. Answer in units of percent. Answer in units of percent.
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 481 were in favor, 402 were opposed, and 119 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 119 subjects who said that they were unsure, and use a 0.01 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? A) the test statistic B) p value C) conclusion
A state highway patrol official wishes to estimate the number of legally intoxicated drivers on a certain road. a) How large a sample is needed in order to be 99% confident that the sample proportion will not differ from the true proportion by more than 5%? b) Repeat part (a) assuming previous studies found that 75% of the drivers on this road are legally intoxicated.
According to an almanac, 60% of adult smokers started smoking before turning 18 years old. (a) If 300 adult smokers are randomly selected, how many would we expect to have started smoking before turning 18 years old? (b) Would it be unusual to observe 270 smokers who started smoking before turning 18 years old in a random sample of 300 adult smokers? Why? (a) We would expect about adult smokers to have started smoking before turning 18 years old. (Type a whole number.) (b) Would it be unusual to observe 270 smokers who started smoking before turning 18 years old in a random sample of 300 adult smokers? A. No, because 270 is greater than u + 2o. B. No, because 270 is less than u - 20. C. No, because 270 is between u - 20 and u + 20. D. Yes, because 270 is greater than u +2o. E. Yes, because 270 is between u - 20 and u + 20.
A computer company wants to determine if there is a difference in the proportion of defective computer chips in a day’s production from two different production plants, A and B. A quality control specialist takes a random sample of 100 chips from the first hour of production from plant A and determines that there are 12 defective chips. The specialist then takes a random sample of 100 chips from the last hour of production from plant B and determines that there are 10 defective chips. Assuming conditions for inference are met, what is the 90% confidence interval for the true difference in proportions of defective chips from a day’s production between the two plants? Find the z-table here.

The National Academy of Science reported that 41% of research in mathematics is published by US authors. The mathematics chairperson of a prestigious university wishes to test the claim that this percentage is no longer 41%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 186 recent articles published by reputable mathematics research journals and finds that 92 of these articles have US authors. Does this evidence support the mathematics chairperson’s claim that the percentage is no longer 41%? Use a 0.05 level of significance. Step 1 of 3: State the null and alternative hypotheses for the test. circle the answer below. H0 p=0.41 ha: p⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯0.41 A.<B.≠C.> Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places Step 3 of 3: Draw a conclusion and interpret the decision. A. We reject the null hypothesis and conclude that there is insufficient evidence at a…
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 488 were in favor, 399 were opposed, and 123 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 123 subjects who said that they were unsure, and use a 0.10 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test.

Joe Biden (Democrat) will be running for President of the United States in 2020. His campaign is continually, among other things, wanting to estimate the percentage of Americans who will vote for him. a) How many Americans should be sampled to estimate the percentage of those who will vote for Joe Biden if his campaign wants to be 95% confident that the margin of error is no more than 2%? The last poll found that 49% of Americans said they will vote for Biden.
A biologist argues that a certain species of fish found in Lake Tanzania in Africa should be classified in a different genus than the currently accepted genus for the species. A simple random sample of standard lengths of fully grown fish from the species in Lake Tanzania is given below: {116.2, 100.3, 118, 152.8, 141.3, 132.8, 95.6, 111.5, 95.2, 95.7} The population of alls such lengths is assumed to be close to normally distributed. Calculate the following interval estimates using this sample (note that the only one of the methods below can be used for a single sample in practice). Round answers to one decimal place accuracy. A 99% confidence interval for the mean of all fully grown fish of this type: type your answer... A 99% prediction interval for the length of one fully grown fish of this type is: type your answer... type your answer... type your answer...
