Question

Consider the following hypothesis statement using 0.05 and data from two independent samples: H0: $\mu_1 = \mu_2$ and Ha: $\mu_1 \neq \mu_2$ $\bar{x}_1 = 23$, $\sigma_1 = 7.6$ and n = 39 $\bar{x}_2 = 24$, $\sigma_2 = 5.8$ and n = 41. Assume the samples are independent and normally distributed with equal variance. Calculate the standard error of the mean. Round to 3 decimal places your final answer.

Consider the following hypothesis statement using 0.05 and data from two independent samples HO: Î¼1 = Î¼2 and Ha: Î¼1 â‰ Î¼2. The sample means are 23.7 and 25.8, with sample sizes of 39 and 41, respectively. Assume the samples are independent and normally distributed with equal variance. Calculate the standard error of the mean. Round your final answer to 3 decimal places.
