The null and alternate hypotheses are: Ho : H1= H2 HI:H # H2 A random sample of 11 observations from one population revealed a sample mean of 23 and a sample standard deviation c 1.1. A random sample of 4 observations from another population revealed a sample mean of 24 and a sample standard deviation of 1.3. The population standard deviations are unknown but assumed to be equal. At the 0.05 significance level, is there a differen between the population means? Required: a. State the decision rule. (Negative amounts should be indicated by a minus sign, Round your answer to 3 decimal places.) The decision nile is to reject Hills or t'sb. Compute the pooled estimate of the population variance. (Round your answer to 3 decimal places.) Pooled estimate of the population vanance c. Compute the test statistic. (Negative amount should be indicated by a minus sign. Round your answer to 3 decimal places.) Test statisticd. State your decision about the null hypothesis. O Do not reject He. O Reject Ho. e. The p-value is O between 0.2 and 0.1. O less than 0.001. O between 0.02 and 0.05. O between 0.001 and 0.01. Obetween 0.05 and 0.1
