answer all
Use the following contingency table to complete (a) and (b) below. a. Compute the expected frequencies for each cell. (rype integers or decimais. Do not round.) b. Compute \( x_{\text {STAT }}^{2} \). Is it significant at \( \alpha=0.005 \) ? Set up the null and alternative hypotheses to test. Choose the correct answer below. A. \( H_{0}: \pi_{1}=\pi_{2} \) B. \( H_{0}: \) Not all \( \pi_{j} \) are equal (where \( j=A, B, C \) ) \( H_{1}: \) Not all \( \pi_{1} \) are equal (where \( j=1,2 \) ) \( H_{1} ; \pi_{A}=\pi_{B}=\pi_{C} \) C. \( \mathrm{H}_{0}: \pi_{\mathrm{A}}=\pi_{\mathrm{B}}=\pi_{\mathrm{C}} \) D. \( H_{0}: \) Not all \( \pi_{j} \) are equal (where \( j=1,2 \) ) \( H_{1}: \) Not all \( \pi_{j} \) are equal (where \( j=A, B, C \) ) \( H_{1}: \pi_{1}=\pi_{2} \)
Compute \( x_{\text {STAT }}^{2} \) \( x_{\text {STAT }}^{2}= \) (Round to three decimal places as needed.) Find the p-value. p-value \( = \) (Round to three decimal places as needed. \( ) \) Is \( \chi_{\text {STAT }}^{2} \) significant at \( \alpha=0.005 \) ? A. Yes, because the p-value is greater than or equal to the level of significance. B. Yes, because the p-value is less than the level of significance. C. No, because the p-value is less than the level of significance. D. No, because the p-value is greater than or equal to the level of cinnificanco
