Answer 1

Here, the hypothesis will be, H₀ : no significant difference between the scores.

v/s H_a : significant difference between the scores.

if, the value of t-calculated> t-tabulated then, in this case, we reject the null hypothesis.

and if the value of t-calculated< t-tabulated then, in this case, we fail to the null hypothesis.

and option, there is no significant difference between the scores.

and option (2) & (3) are not possible because the test is two-tailed.

and here, the option the last one is correct, means Not enough information is known to make a conclusion.
