Is there а difference in cоllege students' GPA fоr STEM mаjоrs compаred to Business majors? A random sample of 80 STEM majors and 80 Business majors reported their current cumulative GPA. The 95% confidence interval to estimate the mean difference (STEM - Business) in college students' GPA was determined to be (-0.487, 0.832). Does this scenario involve matched pairs or two independent samples?[a] Fully interpret the interval in context.With 95% confidence, it is estimated that the [b1] for [b2] college students that are STEM majors is between [b3] points [b4] and [b5] points [b6] than in the Spring semester. Does the interval support that the mean GPA for college students during the Fall semester is significantly different than in the Spring semester?[c]
