In two common species of flowers, A and B, the proportions of flowers that are blue are and , respectively. Suppose that independent random samples of 50 species-A flowers and 100 species-B flowers are selected. Let be the sample proportion of blue species-A flowers and be the sample proportion of blue species-B flowers. What is the mean of the sampling distribution of ? A) Pa- Pb B) Pa/50 - Pb/100 C) Pa^ - PB^ D) Pa(1-pa)/50 + Pb(1-pb)/100 E) √Pa(1-pa)/50 + Pb(1-pb)/100

on edgunuity the answer is c

explanation:

wow this is going to be a long one

cats shouldn't be kept inside their whole life they should be out in nature in the fresh air but because of our technology advances it has become unsafe for our furry friend to be outside in the city's, because they could be hit by vehicles. in city's yes i agree being inside isn't the worse thing, but if you live somewhere rural you should let your cats outside, yes some animals hunt cats but i don't think cats should be kept inside confined to such a small space.

btw this is my opinion
