Hypothesis Test: The system manager is testing whether the actual percentage of spam in the entire population of emails sent to the corporation is 80%.

Based on the provided information, it seems that the system manager conducted a sample analysis to compare the observed sample percentage of spam (76.4%) to the hypothesized population percentage (80%). The next steps would involve performing a statistical hypothesis test, such as a one-sample proportion test, to determine if the observed difference is statistically significant or if it could have occurred due to random chance.
