The probability that the mean height of the American women is between 63 and 64 is 0.6687
The probability of an event occurring is defined by probability. There are numerous instances in real life where we may need to make predictions about how something will turn out. The outcome of an event may be known to us or unknown to us. When this happens, we say that there is a chance that the event will happen or not.
Mean = 63.8
S = 4
n = 100
P(63 <=X-bar<=64) = P(63.638/4/[tex]\sqrt{100}[/tex] < z < 64.638/4/[tex]\sqrt{100}[/tex])
=P(0.2 < z < 0.5)
=P(z<0.5) - P(z<-2)
0.6915 - 0.0228
0.6687
So, the probability is 0.6687
