9.7 Expected counts.
We want to calculate the expected count of companies that use adaptive flexibility and are highly competitive. From Figure 9.1 (pages 459–460), how many companies use adaptive flexibility? What proportion of all companies are highly competitive? Explain in words why, if there is no association between flexibility and competitiveness, the expected count we want is the product of these two numbers. Verify that the formula gives the same answer.
9.7
14. 40.98%. 22.95% of companies use adaptive flexibility, and of that 22.95%, 40.98% of them should be highly competitive assuming no association between flexibility and competitiveness. From the formula, .
