2 Records from previous years for a casualty insurance company show that its clients average a combined total of 2.3 auto accidents per day, with a variance of of the number of accidents per day is not equal to 0.36. A random sample of 20 recent 0.36. The actuaries of the company claim that the current variance, o days had a mean of 2 accidents per day with a variance of 0.78. If we assume that the number of accidents per day is approximately normally distributed, is there sufficient evidence to conclude, at the 0.01 level of significance, that the actuaries are correct? 7 Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) H. :0 O The null hypothesis: The alternative hypothesis: The type of test statistic: (Choose one) The value of the test statistic: (Round to at least three decimal places.) 0 The two critical values at the and 0 0.01 level of significance: (Round to at least three decimal places.) Can we support the claim that the variance of combined total of auto accidents per day differs from 0.362 Yes No X 5 8 =0 * X SE ME > < S
