-Referring to Scenario 18-8, the alternative hypothesis  : At least one of  for j = 1, 2, 3 implies that percentage of students passing the proficiency test is related to at least one of the explanatory variables.

Quizplus · Accepted Answer

The alternative hypothesis states that there is a relationship between the percentage of students passing the proficiency test and at least one of the explanatory variables (attendance, salaries, and spending). Therefore, it is true that the alternative hypothesis is "At least one of the explanatory variables for j = 1, 2, 3 implies that percentage of students passing the proficiency test is related to at least one of the explanatory variables." The alternative hypothesis states that at least one of the explanatory variables is related to the percentage of students passing the proficiency test, which is true in this case based on the multiple regression output given.
