Hi there, I am struggling to determine with test statistic or equation is best for the following scenario?

To understand the impact of unfinished learning, we will measure the average scores of 5^th grade students in math. Are student scores above 60% at a significance level of .05? The goal will be to measure against 4^th and 6^th grade standards. If necessary, a catch-up plan or revised syllabus will be put in place to support children's success in school.

Null hypothesis

H0: = 60% or the average score is equal to 60% or higher.

Alternative hypothesis

H1: 60% or the average score is less than 60%.
