In a random sample of 200 persons of a town,120 are found to be tea drinkers. In a
sample of 500 persons from another town 240 are found to be tea drinkers. Is the
proportion of tea drinkers in the two towns equal. Use 1%LOS
no, if the seccond one was out of 400 people then yes... but as it is out of 500 it is not... 120/200 is simplified into 3/5... and 240/500 is simplified into 12/25 (i don't think it can be simplified furthur

"All other persons" meant all persons who were neither free nor untaxed Indians. Basically, it meant slaves. The phrase "all other persons" was eliminated by Section 2 of the Fourteenth Amendment.
Well, Pythagoras being a person, would have to have been made by another two persons. Unless you're referring to Pythagoras's theorem, in which I'd have to say Pythagoras. His theory was later proved by one of his followers.
In combinatorial terms it makes no difference whether you pick one chairperson out of 12 and five other persons, or you pick 6 persons out of 12 and then they pick one of their subgroup to be chair. Number of ways of selecting 1 out of 12 = 12 That leaves 11 persons and you want 5 from them. this can be done in 11C5 = 11*10*9*8*7/(5*4*3*2*1) = 452 ways. So total number of ways = 12*462 = 5544

1. In a random sample of 200 persons of a town, 120 are found to be tea drinkers. In a random sample of 500 persons of another town, 240 are found to be tea drinkers. Is the proportion of tea drinkers in the two towns equal? Use 0.01 level of significance.
I am the RANDOM champion of the world. LOL i like grapes!!! please give me grapes!!! FEED MEH!!!!!!!!!!! a group of random people
Note that if the first one is multiplied by 2, you get 200*2=400 and 120*2=240. The 240 is the same as in the second test, but the population size is smaller, so the second is less. To test the significance of this difference, you would take 500-400 and divide by some standard deviation. One way to approximate this standard deviation is to say that it is from a binomial distribution with p = the average of 120/200 and 240/500. The standard deviation is sqrt[(average number of people)p(1-p)]. Use this and calculate how many standard deviations there are between the two. Look up this value on the normal distribution table to determine what will be the probability of being differernt.
Persons who do not drink alcoholic beverages are called non-drinkers, alcohol abstainers, or teetotalers. A nonalcoholic. --- Amed
Because of different age-structures of the two populations. In the US, there is a higher proportion of old persons, while in Haiti, there is a higher proportion of young persons. This difference in age structures means that the number of persons who die per unit of time will be higher in the country with a higher proportion of old persons. To avoid this problem, one should use age-standardized mortality rates.
You cannot see another persons friends if their profile is private.
If a persons leg is in the wrong grave, they use proportions to calculate which percentage of the body is missing.
In an adult male it can be as much as 60% by weight. In females the proportion is lower.
