The following results come from two independent samples taken from two populations. sample 1 n? = 43 $\bar{x}_1$ = 20 $s_1$ = 2.22 sample 2 n? = 41 $\bar{x}_2$ = 23 $s_2$ = 7.23 Assume the variances are UNEQUAL. Calculate the standard error. Round your final answer to two decimal places, including the zero before the decimal place needed. E.g., 0.12.

The following results come from two independent samples taken from two populations. We would like to test H0: μ1 – μ2 = 0, α = 0.05 sample 1 sample 2 n1 = 47 n2 = 52 x̄1 = 22.26 x̄2 = 22.3 s1 = 2.23 s2 = 6.62 Assume the variances are UNEQUAL. Calculate the test statistic. Round your final answer to two decimal places, including the zero and the MINUS sign before the decimal place if needed. E.g., -0.12.

Use the formula to find the standard error of the distribution of differences in sample means, x̄1 - x̄2. Samples of size 50 from Population 1 with mean 3.9 and standard deviation 1.9, and samples of size 50 from Population 2 with mean 2.3 and standard deviation 1.4. Round your answer for the standard error to two decimal places. Standard error =
