The expected value (G) can be calculated using the formula:
G = (total number of promotions) * (total number of individuals in the age group) / (total number of individuals)
G = (9 + 29 + 32 + 10) * (48 + 40 + 41 + 41) / (9 + 29 + 32 + 10 + 48 + 40 + 41 + 41)
G = 80 * 170 / 250
G = 13.6
Therefore, the expected value (G) is 13.6.
A study of potential age discrimination considers promotions among managers in a large company. The data are given in the table below. You have to test at a 1% level of significance whether a significant relation between age and promotions exists.
