Ahypothesis will be used to test that a population mean equals 7 against the alternative that the population mean does not equal 7 with known variance σ. what are the critical values for the test statistic upper z subscript 0 for the significance level of 0.04? round your answer to two decimal places (e. g. 98.76).

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
