	The hypothesis testing procedure was probably a t test for dependent means.

Answer 1

=} We can use two- tailed test for hypothesis testing procedure so that this sentence is not probably correct. It is incorrect sentence.

=} The various scale probably used for different variances that's why it is false statement.

=} t - test probably used small samples size.that's why it is false statement.

=}The hypothesis testing procedure for dependent means we probably use t- test. That's why this sentence is mostly true.

Option 4 is correct. It is true.
