Consider The Following Competing Hypotheses And Sample Data Use Table 1 He 180 Ha 180 1 25 T 125 200 A 2 (27.06 KiB) Viewed 21 times
Consider the following competing hypotheses and sample data. Use Table 1. He: $ 180 HA! > 180 1 = 25 T = 125 + = 200 a. Assuming that the sampling distribution of Tis normally distributed, calculate the value of the test statistic (Round final answer to 2 decimal places.) Test statistic b. Find the p-value. 0.05 Picture p value < 0.10 0.025 Picture p-value < 0.05 0 0.01 Picture p-value < 0.025 Op-value Picture 0.10 p-value < 0.01
c. At the 1% significance level, is the median greater than 180? Reject Hg, since the p-value is greater than the significance level. Reject He: Since the p-value is less than the significance level. Do not reject Hg, since the p-value is greater than the significance level. Do not reject Hg, since the p-value is less than the significance level. d. Interpret the results. We conclude that the population median is greater than 180. We cannot conclude that the population median is greater than 180. We conclude that the population mean is greater than 180. We cannot conclude that the population mean is greater than 180
