A company studied the number of lost-time accidents occurring at its brownsville,Texas, plant. historical records show that 6% of the employees suffered lost-time accidents last year. Management believes that a special safety program will reduce suchaccidents to 5% during the current year. In addition, it estimates that 15% of employeeswho had lost-time accidents last year will experience a lost-time accident during thecurrent year.a. What percentage of the employees will experience lost-time accidents in bothyears?
A group committed to quality television has been concerned about a new talk show. For two weeks, they decide to count the number of words that must be "bleeped" as too obscene for television and the number of physical altercations. They hope that after recording this data that they will be able to argue that the show is inappropriate for television particularly during the day. The data for number of words censored is provided below. 34226732115733349254166132289 a) Find the variance and standard deviation.b) What does this information tell you about variability of number of words censored per show?
Erythropoietin (EPO) is a banned drug used by athletes to increase the oxygen-carrying capacity of their blood. New tests for EPO were first introduced prior to the 2000 Olympic Games held in Sydney, Australia. Chance (Spring 2004) reported that of a sample of 830 world-class athletes, 159 did not compete in the 1999 World Championships (a year prior to the new EPO test). Similarly, 133 of 825 potential athletes did not compete in the 2000 Olympic Games. Use a 90% confidence interval to compare the two proportions. Was the new test effective in deterring an athlete’s participation in the 2000 Olympics? Use the CI information to make your conclusion

A statistics instructor believes that fewer than 20% of Evergreen Valley College (EVC) students attended the opening night midnight showing of the latest Harry Potter movie. She surveys 84 of her students and finds that 11 of them attended the midnight showing.At a 1% level of significance, an appropriate conclusion is:There is insufficient evidence to conclude that the percent of EVC students who attended the midnight showing of Harry Potter is less than 20%.
A research team is hired to investigate the prevalence of periodontal disease in a rural countywith a low average socio-economic status. The team is given the task of surveying the area, andproviding a brief examination of participants to correctly identify cases of periodontal diseaseand estimate an overall prevalence. If the team identifies an overall prevalence of above 25%, thesponsoring organization is to initiate an active campaign promoting healthy dental practice. Outof 2,879 participants surveyed, 589 were identified to have periodontal disease. A) Conduct a formal test for detecting if the prevalence of periodontal disease in the sample issignificantly different from the minimum prevalence for intervention. Use an alpha level of 0.01.B) Interpret your conclusions.
A company that sponsors LSAT prep courses would like to be able to claim that their courses improve scores. To test this, they take a sample of 20 people, have each take an initial diagnostic test, then take the prep course, and then take a post-test after the course. The test results are below (scores are out of 100%): Person1234567891011121314151617181920Initial Test7368707979606880637865687367606277647069Post-Test7075767493566987778170817377637578706766 Is there evidence, at an α=0.01α=0.01 level of significance, to conclude that the prep course improves scores? Carry out a Wilcoxon signed rank test, filling in the information requested. (Arrange your data so that the standardized test statistic is for the change from the initial test to the post-test.)

A nonprofit company concerned with the school dropout rates has designed a tutoring program aimed at students between 16 to 18 years old. A national center for educational statistics reported that the high school dropout rate for the year 2000 was 10.9%.One school district, who adopted the use of the nonprofit's tutoring program and whose dropout rate has always been very close to the national average, reported in 2004 that 158 of their 1769 students dropped out. Is their experience evidence that the tutoring program has been effective? Determine the hypotheses for this test. Choose the correct answer below A. H0: p=0.109 HA: p≠0.109 B. H0: p≠0.109 HA: p=0.109 C. H0: p=0.109 HA: p<0.109 D. H0: p=0.109 HA: p≥0.109 E. H0: p≥0.109 HA: p=0.109 F.

Similarly, 133 of 825 potential athletes did not compete in the 2000 Olympic Games. Was the new test effective in deterring an athlete’s participation in the 2000 Olympics? If so, then the proportion of nonparticipating athletes in 2000 will be greater than the proportion of nonparticipating athletes in 1999. Use a 98% confidence interval to compare the two proportions and make the proper conclusion.
