1. Let X denote the mean of a random sample of size 75 from the distribution that has the pdf f (x) =1, 0<=x<=1. Calculate P (0.45 <X< 0.55).
2. Derive the moment-generating function for the normal density.
3. Let Y n (or Y for simplicity) be b (n, p). Thus, Y / n is approximately N [p, p (1...
Definition: when H, K are subgroups of G, we define HK to be the set of all elements of G that can be written in the form hk where h is in H and k is in K.
1) let H be a subgroup of a group G and N be a normal subgroup of G.show that HN is a subgroup of G and N be a normal subgroup of HN.

hi i have a porgraming project.the porblem is
"let agm(a,b) indicate the arithmetic-geometric mean of a and b.
1) plot the solution of agm(a,b)=1.
2) how can we use the result of part 1) to graph agm(a,b)=k for a given k>0?"
arithmatic mean=(a+b)/2 and geometric mean=(a*b)^(1/2)...
