0My colleagues are studying the morphology of Adelie penguin, specifically their flipper length. They are testing Hu=185 mm. If they reject Ho, what type of hypothesis testing error could they have madeDefine this type of error in a sentence.Oa. They could have made a type I (alpha) error. A type I error is when we fail to reject a false HOOb. They could have made a type II (beta) error. A type II error is when we fail to reject a false HOc. They could have made a type I (alpha) error. A type I error is when we reject a true HO.Od. They could have made a type II (beta) error. A type II error is when we reject a true HO.

c) Suppose that the results of carrying out the hypothesis test lead to non-rejection of the null hypothesis. Classify that conclusion by error type or as a correct decision if in fact the mean age at diagnosis of all people with early-onset dementia is less than 55 years old. Suppose that the manufacturer of a new COVID-19 vaccine in South Africa wants to test the null hypothesis Ho: 0 = 0.90 against the alternative hypothesis H₁: 0 = 0.60. She defined her test statistic Y as a number of patients recovered from COVID-19 after an observed twenty trials. If she decided to accept Ho and assume y > 14, i) What will be her Type I error and the power of the test. ii) Explain how the probability of Type II error can be reduced in this case and how it will affect Type I error. Give a practical example.

The survey finds that 15% of the people are 17 years old or younger; 20% are between 18 and 24 years old; 30% are between the ages of 25 and 49; and 35% are 50 years old or older. Use these survey results to answer the following question. What inference can be made about the population as a whole? A. There are more 20-year-olds than 30-year-olds. B. More people are 50 years old than any other age. C. The majority of the population is less than 50 years old. D. There are more people under 24 years old than people over 50 years old. く Q Buscar o ingresar nombre del sitio web & %3D $ 6 7 8 3 4 P R T Y
A peony plant with red petals was crossed with another plant having streaky petals. A nursery owner states that 75% of the offspring resulting from this cross will have red flowers. To test this claim, 100 seeds from this cross were collected and germinated, and 67 plants had red petals. What hypotheses should you use to test the nursery owner's claim? Ho: p = .75 vs. Ha: p * .75 Ho: p = .67 vs. Ha: p = .67 O Ho: p.75 vs. H₂: p= .75 Ho: p ≥.75 vs. Ha: p .75 O A 4. D W P
We want to know if students who drank coffee before an exam performed differently on the exam than those who drank water. We matched participants based on their current grades in the class. Our participants’ scores are presented below: Sample 1: drank coffee: 88, 71, 92, 98, 80, 67, 81 Sample 2: drank water: 89, 95, 66, 73, 85, 70, 61 a. What is tobt? b. Can we reject the null hypothesis?
a) Clearly label and state the appropriate null and alternative hypotheses.b) State your evidence-based conclusion in a well written contextual sentence for a general audience– be sure your conclusion is not about rejecting or not rejecting hypotheses as a general audience2. A newspaper report states that the mean age of commercial jets in the United States is 14 years.An executive of AirJet, a large airline company, claims that the mean age of the planes in his company is lower. He selects a sample of 36 planes and find the mean age to be 11.8 years.Assuming his planes is the same as the national average the chance of this outcome is 0.005.
Assume that, on the average, normal rhesus monkeys spend an mean of 60 minutes dreaming while sleeping at night (thus, μ = 60 minutes). Time spent dreaming is typically referred to as REM sleep (Rapid Eye Movement). You are interested in the effects a new dream-enhancing drug has on dreaming since an increase in the time spent dreaming while sleeping is thought to be a good thing in terms of getting a "restful" sleep. You want to pursue testing the drug in humans if there is any evidence that it significantly increases nightly dreaming time in these nonhuman primates. Ten rhesus monkeys are administered the drug in the morning and their dream time (in minutes) is monitored that night. The alternate hypothesis is: the drug will increase time spent dreaming, or the time in REM sleep. You obtain the following times (minutes) each monkey spent dreaming: 52, 69, 74, 60, 67, 65, 69, 55, 63, 68 Set alpha at a = .01, and complete step 4 of the hypothesis testing procedure, what decision should…
Since an instant replay system for tennis was introduced at a major tournament, men challenged 1389 referee calls, with the result that 420 of the calls were overturned. Women challenged 741 referee calls, and 221 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c) below. A. tes the claim using a hypothesis test B. Test the claim by constructing an appropriate confidence interval c. Based on the results, does it appear that men and women may have equal success in challenging calls?
