1.) Create a set of hypotheses for a test.
More than 11% of people mind if others smoke near a building entrance. Express the null and alternative hypotheses in symbolic form for this claim.H0:H1:
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, 482 were in favor, 403 were opposed, and 124 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 124 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? Identify the null and alternative hypotheses for this test. Choose the correct answer below. О А. Но: р#0.5 H1:p= 0.5 В.

Claim: A minority of adults would erase all of their personal information online if they could. A software firm survey of 554 randomly selected adults showed that 38% of them would erase all of their personal information online if they could. Complete parts (a) and (b) below. ... a. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. (Type an integer or a decimal. Do not round.)

Let’s assume the average income for all majors in the School of Engineering is $80,000. However, the chair of the Computer Science department thinks their students earn more than that. Please choose the appropriate null and alternative hypotheses if the chair wanted to test this belief. a. H0: u <=80,000 Ha: u > 80,000 b. H0: u= 80000 Ha: u not= 80000 c. H0: u >80000 Ha: u < 80000 d. H0: u >80000 Ha: < 80000 e. None of the above.

You are driving home one night and must decide if you have enough gas to get home or not. Use the hypotheses below to answer the questions. Ho: My vehicle has enough gas to get home.Ha: My vehicle does not have enough gas to get home. A. A type I error occurs if I conclude (believe) my vehicle does/does not (circle the correct choice) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice)have enough gas to get home. B. List one possible consequence that could happen if you made a type I error. C. A type II error occurs if I conclude (believe) my vehicle does / does not (circle the correct choice ) have enough gas to get home, but in fact, my vehicle does / does not (circle the correct choice) have enough gas to get home. D. List one possible consequence that could happen if you made a type Il error. E. Based on the seriousness of the consequences of these two errors, we should set a / B to be less than a /B.
