A company are trying to establish if there is a link between the type of fault reported in production and the production method. The number of faulty com- ponents produced is recorded during one week, counted by production method and type of fault. The results are shown in the following table. Fault A Fault B Fault C Fault D Method 1 23 25 16 19 Method 2 27 26 23 23 Method 3 26 23 18 8. Answer the following question parts. (a) Show the calculations that must be done for any two cells when calculating the sample value of the test statistic Q shown here. = 5.90. E, (b) Carry out an appropriate statistical test to determine whether there is a link between the type of fault reported and the production method
