A company claims that its new viral vaccine is at least 90% effective in preventing a contagious viral disease. Suppose that in a clinical trial with 3000 respondents, 2640 did not get infected by this disease. At 1% level of significance, Is the claim of the company valid or not valid?
According to Example 9.17 on p. 257, there is no significant difference, at the 5% level, between towns A and B in their support for the candidate. However, the level α = 0.05 was chosen rather arbitrarily, and the candidate still does not know if he can trust the results when planning his campaign. Can we compare the two towns at all reasonable levels of significance? Compute the P-value of this test and state conclusions.
It is known from experience that in a certain indus-try 60 percent of all labor–management disputes are over wages, 15 percent are over working conditions, and 25percent are over fringe issues. Also, 45 percent of the disputes over wages are resolved without strikes, 70 per-cent of the disputes over working conditions are resolved without strikes, and 40 percent of the disputes over fringe issues are resolved without strikes. What is the probabil-ity that a labor–management dispute in this industry will be resolved without a strike?
suppose that from a sample of 200,000 new york workers, 32,400 reported traveling more than an hour an day. From this information, statisticians determined that about 16.2% of the workers in the state traveled more than an hou to work every day in 2011. If there were 8,437,512 workers in the entire population, about how many traveled more than an hour to work each day?
4. A barangay official claims that at least 95% of theresidents in his area have mobile phones. To test this claim, a researcherrandomly selected a sample of 150 residents and found that 145 of them do have mobile phones. At 1% level of significance, what can you conclude?
A second-stage smog alert has been called in a certain area of Los Angeles County in which there are 50 industrial firms. An inspector will visit 10 randomly selected firms to check for violations of regulations.a. If 15 of the firms are actually violating at least one regulation, what is the pmf of the number of firms visited by the inspector that are in violation of at least one regulation?b. If there are 500 firms in the area, of which 150 are in violation, approximate the pmf of part (a) by a simpler pmf.c. For X = the number among the 10 visited that are in violation, compute E(X) and V(X) both for the exact pmf and the approximating pmf in part (b).
As a result of complaints from both students and faculty about lateness, the registrar at a large university is ready to undertake a study to determine whether the scheduled break between classes should be changed. Until now, the registrar has believed that there should be 15 minutes between scheduled classes. What are the null and alternative hypotheses?
The mayor of a town believes that 28% of the residents favor construction of a new bridge. Is there sufficient evidence at the 0.02 level to dispute the mayor's claim? State the null and alternative hypotheses for the above scenario.
According to the Pew Research Center,on the propotion of the American population who use only a cellular telephone (landline) is 0.37. Jason conducts a survey of one hundred fifty 20 to 24 year olds who live on their own and finds that 73 do not have a landline to their home. Does this provide sufficient evidence to conclude that the proportion of 20 to 24 year olds who live on their own and don't have a landline is greater than 0.37? Use a=0.10 level of significance. A) Verify that nP0(1-P0)>10 and n< 0.05N (Assume the population sizes is N=40 million) B) State the appropiate null and alternative hypotheses. C) Indicate whether the hypothesis is left, right, or two- tailed.
