NON-PARAMETRIC STATISTICS: solve

2. A sample: The sign test (Weighting 5 points) The following table reports the sales of a new tool in a sample of 12 hardware stores in a given month. The shape of the distribution is unknown and, therefore, a parametric statistical test is not appropriate in this case, also considering the small size of the sample. Use the sign test to test the hypothesis that the median sales in the population is greater than 10.0 units per hardware store, using a 5% level of significance. 8189121014167141110 20 I \\ l Translation: (. tools/ hardware)
