You are given the following information about two loss severity distributions fit to a sample of 275 closed claims: . For the exponential distribution, the natural logarithm of the likelihood function evaluated at the maximum likelihood estimate of its one parameter is -828.369. . For the Weibull distribution, the natural logarithm of the likelihood function evaluated at the maximum likelihood estimates of both its parameters is -826.230. . The exponential distribution is a subset of the Weibull distribution. . The null hypothesis is that the exponential distribution provides a better fit than the Weibull distribution. Let x, , be the 10opth percentile of a chi-squared random variable with v degrees of freedom. The following table lists values of x? , for specific combinations of p and v: p = 0.9614 p = 0.9805 p = 0.9983 1=1 4.278 5.456 9.848 1 = 2 6.509 7.875 12.754 Calculate the smallest significance level at which the null hypothesis is rejected
