Independent Samples Test A researcher is interested in investigating the way people problem solve based on how problems are framed. She asks subjects to mount a candle on the wall in such a way that the candle can be upright and it can burn normally. For one group (Group A) she gives participants a candle, a book of matches, and a box of tacks. The other group (Group B) gets a candle, a book of matches and a box of tacks with the tacks separated from the box. How long will it take each group, on average, to solve the problem (measured in seconds). What is the null and alternative hypotheses? Ho = Now conduct the test....
