QUESTION 2 of 4
Can you explain the process for the homework in 4.4 number 23 please?
I only get 30 Choose 15, but I dont know my p or my q.
QUESTION 3 of 4

QUESTION 4 of 4
I'm kind of confused on how to approach these problems (when n is larger than 25 and you cannot use the binomial table)
Use the normal approximation to calculate the probability that P( x >= 17) for n = 30, p = 0.50 .
