A researcher wants to know whether high school GPA and college GPA are significantly different for students attending college on scholarships. Of 40 students asked, she found a mean difference in GPA is -0.10 , with a standard deviation of 0.30 . Given \( \mathrm{a}=0.05 \), what is the correct decision if HO is that college GPA is equal or better than high school GPA?
Reject HO p is less than 0.05
Do not reject H0 p is less than 0.05
Reject \( \mathrm{H} \sim 0 \mathrm{p} \) is more than 0.05
Do not reject HO p is more than 0.05
