The birth weight of babies is normally distributed with a mean of 3.8 kg. A researcher suspects that the weight of babies from mothers who smoked a lot during pregnancy will be lower than the population mean. To examine this, he takes a random sample of 26 babies from mothers who smoked a lot. The mean birthweight in this group was calculated as 3.48 kg with an estimated standard deviation of 0.80 kg. He takes Ho: mu = 3.8 kg,...
