Is it possible to conclude that the risk of death of the textile workers was 2 times higher than the miners?According to the National Center for Health Statistics, in the United States mothers who live in poverty generally have babies with lower birthweight than those who do not live in poverty. While the average birthweight for babies born in the U.S. is approximately 3300 grams, the average birthweight for women living in poverty is 2800 grams. A hospital introduced a prenatal care program to address this problem and enrolled 25 mothers who live in poverty. Babies born to these women had a mean birthweight of 3075g with a standard deviation of 500g. Is the program effective in improving the birthweight of babies born to poor mothers? Assume α = 0.05. Which mean do I use to create my null hypothesis and alternative hypothesis? is this a right-tailed test?
