Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations. (You may find it useful to reference the appropriate table: z table or ttable) H2 20 He: H1 HA: H1 H2 < 0 x₁ = 267 $1 = 37 n₁ = 11 22 = 295 $2 = 31 n2 = 11 a-1. Calculate the value of the test statistic under the assumption that the population variances are equal. (Negative value should be indicated by a minus sign. Round final answer to 3 decimal places.) Test statistic a-2. Find the p-value. O 0.05 s p-value < 0.10 O p-value ≥ 0.10 O p-value < 0.01 O 0.01 s p-value < 0.025 O 0.025 s p-value < 0.05 a-3. Do you reject the pull hypothesis at the 1% level?
