Lundop is a company specializing in rubber-related products. they are known for the durability of their tyres. the mean length of travel a lundop tyre will last (in thousands of miles) is μ = 31. a new tyre design has been brought to the testers in the lundop factory, and it is believed that the mean length of travel has increased with the new design. a hypothesis test is conducted with the following hypotheses: h0: μ = 31 ha: μ > 31 a sample is drawn and a test statistic is calculated. the null hypothesis is not rejected. a report is sent to the design department, saying that the testers proved that the new design does not improve the mean durability of their tyres. a. the report sent to the design department does notaccurately reflect the result of the hypothesis test. b. give your reasons for your answer, and explain the relevance of not rejecting the null hypothesis in a hypothesis test.
