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 such accidents to 5% during the current year. In addition, it estimates that 15% of employees who had lost-time accidents last year will experience a lost-time accident during the current year. Round your answers to three decimal places. a.

Data were collected on lost-time accidents (mean work-hours lost per month over a period of 1 year) before and after an industrial safety program was put into effect at six industrial lants. Here are some of the summary data for Before- After. 4/2 nups:/mIssouri.instructure.com/courses/19617 Find the value of the test statistic needed to conduct the appropriate hypothesis test to determine if the safety program significantly reduced the lost-time accidents. Assume a 0.05 z-1.645 t = 2.0150 t = 0.9421 t...
8/18 Correct Question 12 of 18, Step 1 of 1 A sample of 900 computer chips revealed that 25 % of the chips fail in the first 1000 hours of their use. The company's promotional literature claimed that less than 28 % fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.01 level to support the company's claim? State the null and alternative hypotheses for the above scenario. Answer TablesKeypad Ho: Ha:
