Find the normal approximation for the binomial probability that x = 4, where n = 12 and p = 0.3. Compare this probability to the value of P(x=4) found in Table 2 of Appendix B in your textbook.

You can put this solution on YOUR website!
P(x=4) = (12C4)(0.3)^4(1 - 0.3)^(12 - 4) = 495(0.3)^4(0.7)^8 = 0.23114
