Two groups of students are selected to test different learning techniques. the test scores of group 1 were: 95, 73, 68, 95, 98, 79, 98, 86, 76, 89, 89, 94. the test scores of group 2 were: 100, 80, 95, 90, 95, 98, 100, 100. can it be said with 95% confidence that one group outperformed the other?

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
