(b) Determine Levene's test statistic for this test. Use at least two decimals in your answer.
Test Statistic 6.88
(0) Determine the P-value for this test, to at least three decimal places.
P= 0.005
(d) Using a = 0.05, the null hypothesis should rejected.
From this data and this version of the hypothesis we infer, the
variation in Population 1 is statistically different than the variation in Population 2.
