Ok sweetheart, the easy way to solve these problems is to change them to all the same form for example "decimal" after that you sort them! just don't forget to remember which is which!!! so this is how you solve. 
squared 25, 4.26, 3 1/5 2^3,2.58 
i converted each so your answer is A.
        
             
        
        
        
Answer:
a) 0.4770
b) 3.9945
c) z-statistics seem a large value
Step-by-step explanation:
<u>a. Find the standard deviation of the sample proportion based on the null hypothesis</u>
Based on the null hypothesis:
 : 0.35
: 0.35
and the standard deviation σ =  =
 = ≈0.4770
 ≈0.4770
<u>b. Find the z statistic</u>
z-statistic is calculated as follows:
z= where
 where 
- X is the proportion of employees in the survey who take advantage of the Credit Union ( ) )
 is the proportion in null hypothesis (0.35) is the proportion in null hypothesis (0.35)
- s is the standard deviation (0.4770)
- N is the sample size (300)
putting the numbers in the formula:
z= = 3.9945
 = 3.9945
<u>c. Does the z statistic seem like a particularly large or small value?</u>
z-statistics seem a large value, which will cause us to reject the null hypothesis.
