\fThe accompanying data table includes weights (in grams) of a simple random sample of 40 quarters made before 1964 and weights of 40 quarters made after 1964. When designing coin vending machines. the standard deviations of pre-1964 quarters and post-1964 quarters must be considered. Use the Levene-Brown-Forsythe test and a 0.05 signicance level to test the claim that the weights of pre-1964 quarters and the weights of post-1964 quarters are from populations with the same standard deviation. (3 Identify the test statistic. t=D (Round to three decimal places as needed.)
