ete the problem by hand ((and verify that these answers match the computer output answers). (4m ) Assumptions : 1. Simple Random Samples 2. Independent Samples 3. Normal populations or large n1 and n2 (must assume normal populations because BA treatment sample size is a of 1%. We (reject, t:2P(t>0.37029) fail to reject) Ho and conclude there (is, is not ) a ) = 0.7126 (from online ) difference in the average weekly hours of studying per T BE EXACT, DUE TO ROUNDING course for the BA and BS groups.
