A local retail business wishes to determine if there is a difference in preferred indoor temperature between men and women. A random sample of data is collected, with the following results (note: there are slight differences between Excel and MegaStat output in this test): Using a 0.05 level of significance, can we conclude that there is indeed a difference in the temperature that men prefer compared to women? What is the null hypothesis if we assume men to be group 1 and women group 2? A) µ₁= µ₂_, or µ_d= 0 B) µ₁$\neq$ µ_2, or µ_d$\neq$ 0 C) µ₁- µ₂$\le$ 20 D) µ₁- µ₂ 20
