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. 68,000 58,000 64,000 45,000 69,000 53,000 65,000 47,000 69,000 52,000 x - 57,000 If the population from which the sample was taken has population mean u = 57,000 kilometers, does the sample information here seem to support that claim? In your answer, compute t= s / V10 - and determine from the tables (with 9 d.f.) whether the computed t-value is reasonable or appears to be a rare event. Click here to view page 1 of the table of critical values of the t-distribution. Click here to view page 2 of the table of critical values of the t-distribution. t= (Round to three decimal places as needed.) Since P(T > t) is the computed t-value so the sample information support the claim
