Population variances values are unknown but we know that they are equal (o = 0;). Question: A taxi company is trying to decide whether to purchase brand A or brand B tires for its fleet of taxi: To estimate the difference in the two brands, an experiment is conducted using 12 of each brand. The tires are run until they wear out. The results are Brand A: ī1 36, 300 kilometers, S1 = 5000 kilometers. Brand B: 2 = 38, 100 kilometers, 82 = 6100 kilometers. Compute a 95% confidence interval for uA µB assuming the populations to be approximately normally distributed. Edit View Insert Format Tools Table 12pt v Paragraph v BI U T?v : >
