Question
6. Given a population mean \( \mu = 18.2 \). A sample size \( n = 36 \) with \( \bar{x} = 17.2 \) and \( s = 3.5 \). - **Test if population \( \mu \neq 15 \) at \( \alpha = 0.1 \) level of significance.** 7. Two samples with \( n_1 = 20, s_1 = 8.2 \) and \( n_2 = 15, s_2 = 7.6 \). - **Test if populations \( \sigma_1 \neq \sigma_2 \) at \( \alpha = 0.05 \) level of significance.** Two samples with \( \hat{p}_1 = 0.25, n_1 = 36 \) and \( \hat{p}_2 = 0.3, n_2 = 49 \). - **Test if populations \( p_1 \neq p_2 \) at \( \alpha = 0.05 \) level of significance.** 9. Two independent samples with \( \bar{x}_1 = 5.1, s_1 = 1.2, n_1 = 20 \) and \( \bar{x}_2 = 4.6, s_2 = 1.5, n_2 = 20 \). - **Test if populations \( \mu_1 > \mu_2 \) at \( \alpha = 0.01 \) level of significance.** 10. Two dependent samples with \( \bar{x}_d = 1.6, s_d = 0.8, n_1 = n_2 = 20 \). - **Test if populations \( \mu_1 > \mu_2 \) at \( \alpha = 0.05 \) level of significance.**
