Question
Forty teachers participated in a study of the effectiveness of a teacher training program. Researchers hypothesized that the teachers would show a higher number of explanations of key terms in their lesson plans after the training program than before. What would the null and alternative hypotheses be for this study? Ο Hg: μ220 H1: H<20 Ο H0: μ<20 H1: H> 20 Ο Ηρ: μ= 20 H: µ#20 O Ho: HAfrer - H Before 20 H1: HArer - HBefore <0 O Ho: HAter- HBefore S0 H1: HAfter - HBefore >0 O Ho: HAfter - HBefore =0 H1: HArer - HBefore +0 O Ho: HDuring =HAter = HBefore H1: Not all the means are the same.
