Consider the following competing hypotheses: (You may find it useful to reference the appropriate table: z table or t table) Hypotheses: Ho: MD = 5; HA: MD > 5 Sample results: d = 8.2, SD = 6.4, n = 13 The following results are obtained using matched samples from two normally distributed populations: a. Calculate the value of the test statistic, assuming that the sample difference is normally distributed. (Negative value should be indicated by a minus sign. Round final answer to 3 decimal places.) Test statistic b. Find the p-value. O 0.025 ≤ p-value < 0.05 O 0.01 ≤ p-value < 0.025 O p-value < 0.01 O p-value > 0.10 O 0.05 s p-value < 0.10
c. Use the 10% significance level to make a conclusion. Do not reject Ho since the p-value is more than a. Reject Ho since the p-value is more than a. Do not reject Ho since the p-value is less than a. Reject Ho since the p-value is less than a. d. Interpret the results at a = 0.1. We cannot conclude that that the mean difference is greater than 5. We conclude that the mean difference is greater than 5. We cannot conclude that the mean difference differs from zero. We conclude that the mean difference differs from zero.
