A computer company claims that the batteries in its laptops last 4 hours on average. A consumer report firm gathered a sample of 16 batteries and conducted tests on this claim. The sample mean was 3 hours 50 minutes, and the sample standard deviation was 20 minutes. Assume that the battery time distribution as normal. Test if the average battery time is shorter than 4 hours at α = 0.05. Use the 5-step method. b) Construct a 95% confidence interval...
