A federal report indicated that 27% of children ages 2 to 5 years had a good diet—an increase previous years. How large a sample is needed to estimate the true proportion of children with good diets within 2% with 95% confidence?
sample size n is (t/b)^2 s^2, where t is critical value for conf. level (here 1.96), b is margin of error
(here .02), and s^2 is variance in population (here p(1-p)=.27(.73)=.1971).
So n=(1.96/.02)^2 (.1971) = 1892.9, and round up to 1,893

So i was wondering how to gain weight like which types of food would help a person to gain weight. Right now I’m 145 and i would like to gain 35 pounds in like three months is it possible and if not what type of meal plan would I need to have?
Well – if you want to gain blubber, eat lots of sugar and junk like cereal and rice and potatoes. If you want to gain muscle and bone, eat Atkins – that’s meat, eggs, cheese, nuts and green salad. Most people think of it as a REDUCING diet – but it doesn’t have to be. It’s just good food – with an absence of garbage food. It’s also cheaper overall than garbage food.
Get a used copy of "New Diet Revolution" off of Amazon Books – Atkins can walk you through how the deal works. When you quit eating the sugar, you also feel a lot better.
