A package of light bulbs promises an average life of more than 750 hours per bulb. A consumer group did not believe the claim and tested a sample of 40 bulbs. The average lifetime of these 40 bulbs was 740 hours with ? = 30hours. The manufacturer responded that its claim was based on testing hundreds of bulbs. b.Given the usual sampling assumptions, is there a 95% probability that 750 lies in the 95% confidence interval of the manufacturer? c.If...
