Suppose babies born in a large hospital have a mean weight of 3366 grams, and a variance of 244,036 . If 118 bables are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by less than 45 grams? Round your answer to four decimal places.

27-40 a Factorice el polinomio \( y \) use la forma factorizada para ha- Ilar los ceros. A continuación, trace la grafica. \( \begin{array}{ll}\text { 27. } P(x)=x^{3}-x^{2}-6 x & \text { 28. } P(x)=x^{3}+2 x^{2}-8 x \\ \text { 29. } P(x)=-x^{3}+x^{2}+12 x & \text { 30. } P(x)=-2 x^{3}-x^{2}+x \\ \text { 31. } P(x)=x^{4}-3 x^{3}+2 x^{2} & \text { 32. } P(x)=x^{5}-9 x^{3}\end{array} \)
