The total number of working days for company C is 322 + 323 + 312 + 311 + 311 + 310 = 1889, giving an average of 1889 / 6 = 314.83 days. The total number of working days for company E is 301 + 298 + 308 + 310 + 322 + 321 = 1860, giving an average of 1860 / 6 = 310 days. The difference between their averages is 314.83 - 310 = 4.83, which is approximately 5.
