The alternative hypothesis states that at least one of the explanatory variables has an effect on the percentage of students passing the proficiency test, which is true in this case. The alternative hypothesis states that at least one of the explanatory variables (Salaries and Spending) affects the percentage of students passing the proficiency test. Therefore, it is true that the percentage of students passing the proficiency test is affected by at least one of the explanatory variables.
