The Iris data set is perhaps the best-known data set in statistics used in FLA. Fisher's classic 1936 paper. The sepal length of one of the Iris speciessetosa is assumed to come from a normal distribution with an average length of 8.8 cm, with a standard deviation of 1.31 cm. Use the method for solving probability problems and Excel to find the following probabilities. 1. (1 mark} What is the probability that the sepal length of ms setosas in this population is less than 8.17 cm? = (3dp) 2. (1 mark} What is the probability that the sepal length of his setosas in this population is greater than 8.4 cm? = (3dp) 3. (1 mark} A mature Iris setosas from this population must be between 8.74 cm and 9.61 cm long. What is the probability that an In's setosas from this population is within this limit for length? = {Sdp} 4. (1 mark} If 15 Iris setosas are selected from this population, how many would be expected to be between 8.74 cm and 9.61 cm long? = (Sdpl
