A random sample of n₁ = 10 regions in New England gave the following violent crime rates (per million population). X₁: New England Crime Rate 3.3 3.7 4.0 4.1 3.3 4.1 1.8 4.8 2.9 3.1 Another random sample of n₂ = 12 regions in the Rocky Mountain states gave the following violent crime rates (per million population). X₂: Rocky Mountain Crime Rate 3.5 4.3 4.7 5.1 3.3 4.8 3.5 2.4 3.1 3.5 5.2 2.8 LAUSE SALT Assume that the crime rate distribution is approximately normal in both regions. (a) Use a calculator to calculate x₁, S₁, X₂, and s₂. (Round your answers to four decimal places.) X₁ M x X2 x x (b) Do the data indicate that the violent crime rate in the Rocky Mountain region is higher than in New England? Use a = 0.01. (1) What is the level of significance? x
What is the value of the sample test statistic? (Test the difference ₁-₂. Round your answer to three decimal places.) X
