A study involves a population of 400 tall women. This population has a mean height of 179.832 cm and a standard deviation of 12.192 cm. If 50 of these women are randomly selected, find the probability that the mean for this sample group is above 182.88
Answers: 2
of 179.832 cm and a standard deviation
of 12.192 cm. ![P(\overline{X}182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z](/tpl/images/0908/6748/aaa77.png)
