Suppose you've run a regression relating Revenues to TV Ads and Online Ads. You are willing to make the necessary assumptions to deduce causality and run hypothesis tests. Your results are as follows: CoefficientsStandard Errort-StatP-valueIntercept5988.0431072202.1367652.7191967380.006881952TV Ads199.632021227.826586737.1741469124.63154E-12Online Ads53.5209242941.08181151.3027888090.193533758If you tested the null hypothesis that Online Ads have no impact on Revenues at the 90% confidence level (i.e., 90% degree of support), you would:
A. Fail to reject, and conclude Online Ads do impact Revenues
B. Fail to reject, and conclude there is insufficient evidence to establish that Online Ads impact Revenues

Luz, a woman with a history of asthma, walked by a house and noticed that smoke was pouring out of the basement. Evidently, any smoke detector was either absent or not working because nobody in the home was reacting to the emergency
Luz banged on the front door and threw it open, screaming that there was a fire. The family immediately rushed out, but upon reaching the safety of the front lawn, one of the children said the cat was trapped inside. Luz dashed into the now smoke-filled structure, searched around, found the cat, and emerged with the frightened but safe creature. According to the chapter, what short- and long-term problems will Luz most likely have?

A) ionic bonds are much stronger than covalent bonds. B) in ionic bonds, two atoms share electrons, whereas in covalent bonds, one atom gives one or more electrons to the other atom.
