For this problem, use datasetbreaking.txtalong withR. An experiment was conducted to select the supplier of raw materials for production of a component. The breaking strength of the component (columnbreaking) was the objective of interest. Four suppliers were considered (columnsupplier). The four operators (columnoperator) can only produce one component each per day

1. (a)Create histogram of breaking strength and label the axes properly. Comment on the shape of the distribution.
2. (b)Find the five number summary and the standard deviation for the variable breaking strength.
3. (c)Create proper graphical display to compare the breaking strength distributions of the four different suppliers and label the axes properly. Which supplier would you recommend? Justify your answer with a brief sentence.
4. (d)Suppose the breaking strength for operator 3 on day 2 was entered incorrectly and should have been 600 instead of 540. How would your answer in part (b) change?
