please explain how to solve for probability...
If i have a class of 14 males and 36 females and the professor selects a name from the class using random sampling what is the probability that the first student selected will be a female?
If the random sample of n=3 students is selected and the first two are both females what is the probability that the third student selected will be a male?
If i have a mean = 0
standard deviation =1
z= -2.25 and z= +2.25
z= -2.50 and z = +2.50
z= - 0.70 and z= +0.70

2. Since we select 3 students, first two are females. ...
The solution gives detailed steps on computing probability using random sampling and using standard normal distribution.
Probability of Proportions
A given population proportion is .25. For the given value of n, what is the probability of getting each of the following sample proportions?
a. n = 110 and p̂ ≤ .21
b. n = 33 and p̂ > .24
c. n = 59 and .24 ≤ p̂ < .27
d. n = 80 and p̂ < .30
e. n = 800 and p̂ < .30View Full Posting Details
