A taxi company tests a random sample of 10 steel-belted radial tires of a certain brand and records the tread wear kilometers, as shown below. in 66,000 68,000 59,000 69,000 44,000 52,000 54,000 61,000 68,000 63,000 If the population from which the sample was taken has population mean μ = 59,000 kilometers, does the sample information here seem to support that claim? In your answer, compute t= x-59,000 S/√10 and determine from the tables (with 9 d.f.) whether the computed t-value is reasonable or appears to be a rare event.
