Question

Consider the following hypothesis statement using 0.05 and data from two independent samples: H0: $\mu_1 = \mu_2$ and Ha: $\mu_1 \neq \mu_2$ $\bar{x}_1 = 20.3$, $\sigma_1 = 17.0$ and n = 33 $\bar{x}_2 = 20.8$, $\sigma_2 = 17.05$ and n = 41 Assume the samples are independent and normally distributed with equal variance. Calculate the test statistic. Round to 3 decimal places your final answer.

          Consider the following hypothesis statement using 0.05 and data from two independent samples:
H0: $\mu_1 = \mu_2$ and Ha: $\mu_1 \neq \mu_2$
$\bar{x}_1 = 20.3$, $\sigma_1 = 17.0$ and n = 33
$\bar{x}_2 = 20.8$, $\sigma_2 = 17.05$ and n = 41
Assume the samples are independent and normally distributed with equal variance.
Calculate the test statistic.
Round to 3 decimal places your final answer.

Consider the following hypothesis statement using 0.05 and data from two independent samples:
H0: μ1 = μ2 and Ha: μ1 ≠μ2
x̅1 = 20.3, σ1 = 17.0 and n = 33
x̅2 = 20.8, σ2 = 17.05 and n = 41
Assume the samples are independent and normally distributed with equal variance.
Calculate the test statistic.
Round to 3 decimal places your final answer.
