- Which of the following statements about hypothesis testing iS correct? o In hypothesis testing, sample data are used to test claims about the value of population parameters. o In hypothesis testing, population data are used to test claims about the value of sample statistics. In hypothesis testing, population data are used to test claims about the value of population parameters. o None of the above statements are true. 0 耳1.) A survey of 80 random Americans showed that 5 are naturally blonde.A Google search says that 5% of Americans are blonde. At x=0.05,test this claim.Use: a.) a hypothesis test b.)an appropriate ClSuppose that people were asked "would you leave your current job to make more money at a new job?", and the following table with the responses to the question as well as the generation that the subject belonged to was constructed: "Leave Job for More Money" "Baby Boomer" "Millenial" Yes 115 175 No 165 185 If a Test of Independence is performed on this table to determine if "Generation" and "Willingness to Leave a Job for More Money" are independent of each other, then calculate the value of the Test Statistic (TS) that you would get when running this hypothesis test. Round off your answer to the third decimal place: The TS in this problem, rounded off as instructed, is:
- A survey of high school girls classified them by two attributes: whether or not they participated in sports and whether or not they had one or more older brothers. Participated In sports Participated In sports Older brother Yes No Total Yes 12 8 20 No 13 27 40 TOTAL 25 35 60 A) Use the following data to test the null hypothesis that these two attributes of classification are independent. B) Suppose we do the below hypothesis test instead: H0: P1 - P2 = 0 H1: P1 - P2 ≠ 0 where, P1 ==>Propotion of young girls participated in sports of those who have a brother P2 ==> Propotion of young girls participated in sports of those who do not have a brother. What would be the test statistic and the p-value for this test?Which of the following hypothesis is considered one tail test? O a. HO: μ> 80 O b. HO: μ #80 O c. H1: μ ≥ 80 O d.

Suppose that we have reason to believe otherwise and wish to carry out a hypothesis test for this claim. State the null hypothesis H, and the alternative hypothesis H, that we would use for this test. H, :0 H, :0 OWhat are the two decisions that you can make from performing a hypothesis test? What are the two decisions that you can make from performing a hypothesis test? Select all that apply. A. fail to reject the alternative hypothesis C. accept the null hypothesis E. fail to reject the null hypothesis G. reject the null hypothesis B. reject the alternative hypothesis D. accept the alternative hypothesis F. make a type II error H. make a type I errorAfter the football team once again lost a game to the college's archrival, the alumni association conducted a survey to see if alumni were in favor of firing the coach. An SRS of 100 alumni from the population of all living alumni was taken. Sixty-four of the alumni in the sample were in favor of firing the coach. Let p represent the proportion of all living alumni who favor firing the coach. The decision made from the above hypothesis test is that: O the observed sample proportion is not statistically significant, and the null hypothesis should be rejected. O the observed sample proportion is statistically significant, and the null hypothesis should be rejected. O the observed sample proportion is statistically significant, and the null hypothesis should not be rejected. O the observed sample proportion is not statistically significant, and the null hypothesis should not be rejected.Normally only about 19% of people who try to quit smoking succeed, but sellers of a motivational tape claim that listening to their recorded messages can help people quit (i.e., more than 19% of the people who use the tapes will successfully quit). Let p represents the percentage of people who have listened to the recorded messages and have successfully quit. Match the appropriate null and alternative hypotheses, based on the sellers' claim. H,: p = 0.19 p> 0.19 p2 0.19 ps 0.19 p 0.19 p2 0.19 ps 0.19 p < 0.19 Op- 0.19 Do you consider a Type I or Type Il error a more serious mistake here? Why? Your answer should make it clear what Type I and Il errors are in this context.SEE MORE QUESTIONSRecommended textbooks for youMATLAB: An Introduction with ApplicationsStatisticsISBN:9781119256830Author:Amos GilatPublisher:John Wiley & Sons Inc
