Answer:
Step-by-step explanation:
Factorize 175 and 50
175 = 5 * 5 * 7
50 = 5 * 5 * 2
![\frac{\sqrt[3]{175}}{\sqrt[3]{}50}=\sqrt[3]{\frac{175}{50}}\\\\\\ =\sqrt[3]{\frac{5*5*7}{5*5*2}}\\\\\\=\sqrt[3]{\frac{7}{2}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B175%7D%7D%7B%5Csqrt%5B3%5D%7B%7D50%7D%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B175%7D%7B50%7D%7D%5C%5C%5C%5C%5C%5C%20%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B5%2A5%2A7%7D%7B5%2A5%2A2%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B7%7D%7B2%7D%7D)

Answer:
a) The probability that 71 of 150 will prefer boy child is 71/150 or 0.47
b) The result contradicts the poll actual percentage is 47.33% which is 3.33% more than the poll predicted
Step-by-step explanation:
If 71 out of 150 prefer boy child
The probability that the 71 will prefer boy child is
= 71/150
The actual percentage is
(71/150)*100%
= 47.33%
This contradicts the poll as this is more than the poll predicted. That means Less than 71 of 150 actually preferred boy child.
325.81
