Does secondhand smoke increase the risk of a low weight birth? A baby is "low birth weight" if it weighs less than 5.5 pounds at birth. According to the National Center of Health Statistics, about 7.8% of all babies born in the U. S. are categorized as low birth weight. Researchers randomly select 1200 babies whose mothers had extensive exposure to secondhand smoke during pregnancy. 10.4% of the sample are categorized as low birth weight. Which of the following are the appropriate null and alternative hypotheses for this research question. Group of answer choices H 0 H 0 H 0 : p = 0.078 p = 0.078 p = 0.078 H a H a H a : p ≠ 0.078 p ≠ 0.078 p ≠ 0.078 H 0 H 0 H 0 : p = 0.78 p = 0.78 p = 0.78 H a H a H a : p > 0.78 p > 0.78 p > 0.78 H 0 H 0 H 0 : p = 0.104 p = 0.104 p = 0.104 H a H a H a : p ≠ 0.104 p ≠ 0.104 p ≠ 0.104 H 0 H 0 H 0 : μ = 0.104 μ = 0.104 μ = 0.104 H a H a H a :
