Does a statistics course improve a student's mathematics skills, as measured by a national test? Suppose a random sample of 13 students takes the same national mathematics exam prior to enrolling in a stats course and just after completing the course. At a 1% level of significance determine whether the scores after the statscourse are significantly higher than the scores before. Take the differences = before - after.BeforeAfter430465485475520535360410440425500505425450470480515520430430450460495500540530What type of alternative hypothesis is appropriate for this research question?O one-sidedO two-sidedLocate student 9 in the dataset.
