A Gallup poll was conducted in 2010 in which they surveyed people all over the world and found that 44% of adults in the world believe that global warming is a serious threat to themselves and their families. Assume that this is the population proportion of adults worldwide who believe global warming is a threat (p= 0.44), and suppose we repeatedly select random samples of size 250, and ask them the same question. (a) Find the mean, and standard error,...
