A tire company claims that their new tires will have an average life of 122000 miles. A consumer group wishes to test this claim at the a = 0.05 level of significance. Which would be correct hypotheses for this test? O Ho:u = 122000, H : µ # 122000 o Ho:u = 122000, H1 : µ < 122000 Ho:u < 122000, H : µ = 122000 Ho: # 122000, H1 : µ = 122000 o Ho:u = 122000, H1: µ > 122000 A random sample of 46 sets of tires were tested and had an average life of 121945 miles, with a standard deviation of 66.8 miles. Find the test statistic (2 decimal places): Give the P-value (4 decimal places, if less than 0.001 answer 0): Which is the correct result: O Do not Reject the Null Hypothesis O Reject the Null Hypothesis Which would be the appropriate conclusion? o There is not significant evidence to suggest that the average life of the tires is different than 122000
