Problem 1: Data from 10 basil (Ocimum basilicum: 2n — 72) plants have been scored and given below: From the given data can you draw (using suitable statistical test) a relation between cytological attributes and pollen fertility. Proof. In the order statistic experiment, select the standard uniform distribution and n = 5. Vary k from 1 to 5 and note the shape of the probability density function of X_ { (k)}. For each value of k, run the simulation 1000 times and compare the empirical density function to the true probability density function.
