The null and alternate hypotheses are: H0 : μ1 = μ2 H1 : μ1 ≠ μ2 A random sample of 11 observations from one population revealed a sample mean of 25 and a sample standard deviation of 3.5. A random sample of 4 observations from another population revealed a sample mean of 29 and a sample standard deviation of 4.5. At the 0.01 significance level, is there a difference between the population means? State the decision rule. (Negative values should be indicated by a minus sign. Round your answers to 3 decimal places.) Compute the pooled estimate of the population variance. (Round your answer to 3 decimal places.) Compute the test statistic. (Negative value should be indicated by a minus sign. Round your answer to 3 decimal places.) State your decision about the null hypothesis. multiple choice 1 Do not reject H0. Reject H0. The p-value is multiple choice 2 between 0.1 and 0.05 less than 0.001 between 0.02 and 0.05 between 0.001 and 0.01 between 0.1 and 0.2
