Question 1197827
Binomial: n = 25, p = .47
Note: We can use the normal distribution as a close approximation to the
 binomial distribution whenever np > 5 and nq > 5. Satisfied.

 Describe the shape, center, and spread of the sampling distribution
x-bar = np = 11.75  and s = {{{sqrt(25*.47*.53)}}} = 2.5
{{{drawing(400,200,-5,20,-1,1, 
graph(400,200,-5,20,-1, 1,.16*exp(-(x-11.75)^2/(2*2.5^2)))) }}}
