Paper is being manufactured continuously before being cut and wound into large rolls. The process is monitored for thickness (using a calliper). A sample of 12 measurements on paper, in micrometres, yielded: 11. 56, 10. 21, 11. 54, 11. 73, 11.90, 11. 36, 12. 72, 13. 36, 13. 04, 11. 56, 12. 13, 12. 20 Use Matlab to answer the following questions. a) Find the five-number summary for these observations. (Enter your answer correct to 2 decimal places) b) Find the average thickness. (Enter your answer correct to 2 decimal places) c) Find the standard deviation of thickness. (Enter your answer correct to 2 decimal places) d) By constructing an appropriate visual display of the data, determine which description below best matches the distribution of paper thickness Bimodal, fairly symmetric, no outliers Not enough information to say Unimodal, right-skewed, with some apparent outliers O Unimodal, right-skewed, no outliers O Unimodal, fairly symmetric, no outliers Unimodal, fairly symmetric, with some apparent outliers
