Part A:
Given that i<span>n
a population of 210 women, the heights of the women are normally
distributed with a mean of 64.4 inches and a standard deviation of 2.9
inches.
If 36 women are selected at random, the mean of the sample is estimated by the mean of the population.
Thefore, the mean is given by:

Part B:
The standard deviation using the finite population factor is given by:

Answer:
11
Step-by-step explanation:
because the length of 12 is the same of t+1 so 11+1=12
youre welcome
1/3= 5/15
2/5= 6/15
5/15 + 6/15 = 11/15
15/15 - 11/15 = 4/15
Part C= 4/15
Answer:
-67
Step-by-step explanation:
2^3-(3*5^2)
simplify exponents
8-3*25
8-75
=-67
1 1/3 - 5/6
Find common demoninator which is 6.
Then do 2*1=2.
Now you got 2/6 - 5/6 = -3/6
Simplify:
-3/6=-1/2
Then combined answers.
1 - 1/2 = 1/2
Final answer is 1/2
