CONFIDENCE INTERVALS
Student ’ s t-test • The value of t will be compared to values in the specific table of "t distribution test" at the value of the degree of freedom. • If the value of t is less than that in the table, • If the value of t is less than that in the table, then the difference between samples is insignificant: i.e., the null hypothesis is accepted. • If the t value is larger than that in the table so the difference is significant: i.e., the null hypothesis is rejected.
