Q2 (a) A research has been conducted an experiment to compare the deflection (um) between two types of material for cutting tool in milling machining process. About 30 samples of cutting tool for material A and 30 of cutting tool for material B has been used for during the test. Table Q2(a) shows several descriptive statistics represent the data of tensile strength. Table Q2 (a) Descriptive statistics for deflection (um) Material Number Minimum Q1 median Q3 Maximum of value value specimen A 30 0.462 3.453 6.415 8.548 13.599 B 30 0.2 2.037 4.157 7.716 15.491 (i) Plot a box plot based on recorded data given in Table Q2(a) (ii) Based on the box plot, which material of cutting tool is have better performance?State your reason (iii) Suppose that material A produce deflection of 4.4 um. The data is wrongly recorded as 44 um. What you can interpret about the box plot? (iv) Calculate the value of IQR for both materials
