In a test of the hypothesis that vehicle speeds are normally distributed, a χ 2 test was applied to a sample size of 100. The estimated mean and standard deviation were 40.8 and 9.31 mph, respectively. The number of intervals used in the test was seven; the observed statistic was d1 = 4.506. Is the evidence such as to reject the hypothesis at the 10 percent level? If the hypothesis is true, what is the likelihood that a similar sample and test would lead to a test statistic greater than 4.506? (That is, what is the "p level" of the observed statistic?)
