A: This is a problem of 2 sample proportion testing,
Consider a drug test company that provides a test marijuana usage. Among 292 tested subjects, results from 30 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test are wrong.

- f our null hypothesis is H0: ? = 40, what are the three possiblealternative hypotheses?A physician wants to test two blood glucose meters to see if there is any differences in measurements. To do this, he measures the glucose in blood samples taken from several randomly selected patients with both meters. Identify the null and alternative hypotheses for a hypothesis test, where each difference is calculated by subtracting the measurement on the second meter from the measurement on the first meter. A. H0:μd=0 Ha:μd>0 B. H0:μd=0 Ha:μd≠0 C. H0:μd=0 Ha:μd<0 D. H0:μd≠0 Ha:μd=0The null hypothesis H0 maintains the status quo, while the alternate hypothesis Ha seeks to change the status quo. Label the pair members as null or alternate hypotheses.
- A company selling home furnaces claims that installingtheir new high efficiency furnace will “cut your heating bill in half.” A consumer agency collects data for a ran-dom sample of homes and plots this year’s heating costs with the new furnaces against previous costs with the oldfurnaces. Which are the most appropriate hypotheses totest the company’s claim?A) H0: b = 0, HA: b ≠ 0B) H0: b = 0, HA: b 7 0C) H0: b = 0, HA: b 6 0D) H0: b = 0, HA: b 6 0.5E) H0: b = 0.5, HA: b ≠ 0.5The average American consumes 9.8 liters of alcohol per year. Does the average college student consume less alcohol per year? State your null and alternative hypothesis H0:H0: Ha:Ha:For the given scenario, determine the type of error that was made, if any. (Hint: Begin by determining the null and alternative hypotheses.) A pharmaceutical company claims only 2% as the percentage of people taking a particular drug that experience significant side effects. One researcher claims that the percentage of people taking a particular drug that experience significant side effects is less than 2%. The researcher conducts a hypothesis test and fails to reject the null hypothesis. Assume that in reality, the percentage of people taking a particular drug that experience significant side effects is 0.5%. Was an error made? If so, what type?
- State the null and alternative hypotheses: H0: μ | ≠, <, =, or > _________ H1: μ | ≠, ≥ , =, ≤ , or = _________For each pair of hypotheses that follows, decide whether H₀ and H₁ are set up correctly as the null and alternative hypotheses for a hypothesis test. If so, select “Valid” from the drop down menu. If not, select “Invalid”. 1 H₀: μ ≠ 230 2 H₀: M = 50 H₁: μ = 230 H₁: M ≠ 50 3 H₀: μ = 150 4 H₀: µ = 135 H₁: μ ≠ 158 H₁: µ ≠ 135 You evaluate the by assuming that it is true and testing the reasonableness of this assumption by calculating the probability of getting the results if chance alone is operating.Suppose an engineering firm is asked to check the safety of a dam. A) What kind of mistake would be made if the Ho (null hypothesis) that the dam is safe is wrongly rejected? B) What kind of mistake would be made if the Ho that the dam is safe is wrongly accepted?
- A toy manufacturer claims that the meantime that its top-selling toy captures children's attention is at least 20 minutes. Suppose that we doubt this claim and we carry out a hypothesis test to see if we can refute the claim. State the null hypothesis H0 and the alternative hypothesis H1 that we would use for this test.If your null and alternative hypothesis are:H0:μ=64H0:μ=64 H1:μ<64H1:μ<64Then the test is:After a researcher states an alternative hypothesis, the null hypothesis would be stated in a way that makes the two hypotheses ________ and ________. assumed; independent equal; independent all-inclusive; mutually exclusive equal; robust
