The application of a t-test determines whether a linear relationship exists between a family’s educational level and the eliteness of the institution that the first child went.

Null hypothesis (H0): p= 0
Alternative hypothesis (HA): p≠0
Test statistic (t*) = r√n-2/√1-r2
The correlation coefficient between educational status and eliteness is r while n is the sample size.
