(19-3) One hundred rats whose mothers were exposed to high levels of tobacco smoke during pregnancy were put through a simple maze. The maze required the rats to make a choice between going left or right at the outset. Eighty went right when running the maze for the first time. Assume that the 100 rats can be considered an SRS from the population of all rats born to mothers exposed to high levels of tobacco smoke during pregnancy. Let p be the proportion of rats in this population that would go right when running the maze for the first time. Which of the following is a large-sample 90% condence interval for p? A. 0.8 i .040 B. 0.8 i .066 C. 0.8 i .078
