Consider the following hypotheses. H?: ?? ? 30 H?: ?? > 30 Given that ?? = 7, n = 43, ?? = 32, and ?? = 0.05, calculate ??. The probability of committing a Type II error, ??, is . (Round to four decimal places as needed.)

Step 1
Given that Ī± = 0.05 and it is a right-tail test, the critical value is 1.64 (obtained from the z-table). Critical value = 1.64 * 7 / ā43 + 32 = 31.76 Therefore, the critical region is xĢ > 31.76. Show moreā¦

Consider the following hypotheses: H0: p ā„ 0.39 HA: p < 0.39 Which of the following sample information enables us to reject the null hypothesis at Ī± = 0.05 and at Ī± = 0.10? (You may find it useful to reference the appropriate table: z table or t table) (Round all intermediate calculations to at least 4 decimal places.) Ī± = 0.05 Ī± = 0.1 a. x = 40; n = 129 b. x = 76; n = 292 c. pĢ = 0.37; n = 45 d. pĢ = 0.37; n = 392
