Consider the following small sample of five (n = 5) chemical yields: 784 801 814 820 836 Using this information, conduct a small sample Sign Test of the hypothesis that the population median of chemical yields exceeds 750 (assume a 0.05 level of significance). Show your work by using the binomial distribution (or table) to calculate the p-value and provide the test results.

Consider the following small sample of five (n = 5) chemical yields: 784 801 814 820 836 Using this information, conduct a small sample Sign Test of the hypothesis that the population median of chemical yields exceeds 750 (assume a 0.05 level of significance). Show your work by using the binomial distribution (or table) to calculate the p-value and provide the test results. A botanist believes that the median height of a particular plant exceeds 20 inches in the population. A random sample of 15 (n = 15) plants is taken and 13 of those have a height above 20 inches. Use the large sample version of the Sign Test at the 0.05 level to test the botanist's claim. You should not show your work for this problem. Simply report the z test statistic, the decision rule, the the test results.
