Consider the following competing hypotheses and accompanying sample data. (You may find it useful to reference the appropriate table: z table or table) HO: Pi - P2 2 0 HA: P1 - D2 < 0 X1 = 223 ni = 418 x2 = 245 n2 = 418 a. Calculate the value of the test statistic. (Negative value should be indicated by a minus sign. Round final answer to 2 decimal places.) Test statistic b. Find the p-value. O 0.01 Picture p-value < 0.025 O 0.025 Picture p-value < 0.05 0.05 Picture p-value < 0.10 O p-value Picture 0.10 p-value < 0.01
c. At the 10% significance level, what is the conclusion to the test? O Reject Ho since the p-value is less than significance level. Reject Ho since the p-value is greater than significance level. Do not reject Ho since the p-value is less than significance level. Do not reject Ho since the p-value is greater than significance level. d. Interpret the results at a = 0.10. We conclude that the population proportions differ. We cannot conclude that the population proportions differ. We conclude that population proportion 2 is greater than population proportion 1. We cannot conclude that population proportion 2 is greater than population proportion 1.
