2. A sample of 20 OU freshmen had a GPA over all of their first semester classes of 2.8 with a variance of 0.25 (remember: standard deviation is the square root of variance). Perform a hypothesis test at LaTeX: \alpha\:=\:0.05\:\:α = 0.05to determine if the first semester GPA of all freshmen is less than 3.0.

What is the null hypothesis?

What is the alternative hypothesis?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
