Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 =  = 475
 = 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation, = 475
 = 475
Margin of Error, ME = 100
 = 1 - 0.90 = 0.10
 = 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64
Find sample size, n:
n ≥ ![[Z_\alpha_/_2 * (\frac{\sigma}{ME})]^2](https://tex.z-dn.net/?f=%20%5BZ_%5Calpha_%2F_2%20%2A%20%28%5Cfrac%7B%5Csigma%7D%7BME%7D%29%5D%5E2%20) 
 
n ≥ ![[1.64 * (\frac{475}{100})]^2](https://tex.z-dn.net/?f=%5B1.64%20%2A%20%28%5Cfrac%7B475%7D%7B100%7D%29%5D%5E2) 
 
n ≥ 60.68
≈ 61
Minimun sample size,n = 61
 
        
             
        
        
        
The answer is FALSE, the mode in a sequence is the number that appears most often; the mode is 2.
        
             
        
        
        
we are given 
A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 47 states
so, the number of ways of selecting four specific capitals out of 47 states is



now, we can find probability
so, the probability is

The odds of getting a red first is 5/12. the odds of getting a green second is 7/11. the probability of both is then 5/12 * 7/11, or 35/132
