A taxi company tests a random sample of 10 steel-belted radial tires of a certain brand and records the tread wear in kilometers, as shown below. 67,000 68,000 62,000 67,000 47,000 61,000 45,000 55,000 61,000 64,000 x - 51,000 If the population from which the sample was taken has population mean u = 51,000 kilometers, does the sample information here seem to support that claim? In your answer, compute t = and s/ 1 10 determine from the tables (with 9 d.f.) whether the computed t-value is reasonable or appears to be a rare event.
