Answer:
Divide a percent by 100 and remove the percent sign to change it  from a percent to a decimal.
Step-by-step explanation:
1. Example: 9 % is 0.09 
2. Example: 8% is 0.08
3 .Example: 10% will change to 10/100 =decimal 0.10
That how it work just follow the example 
 
        
                    
             
        
        
        
Answer:
We can assume that the statistic is 

So the p value obtained was a very high value and using the significance level given  we have
 we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
 so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
Step-by-step explanation:
Concepts and formulas to use  
We need to conduct a hypothesis in order to test the claim that the true proportion is equal to 3/5 or not.:  
Null hypothesis: 
  
Alternative hypothesis: 
  
When we conduct a proportion test we need to use the z statistic, and the is given by:  
 (1)
 (1)  
The One-Sample Proportion Test is used to assess whether a population proportion  is significantly different from a hypothesized value
 is significantly different from a hypothesized value  .
.
Calculate the statistic  
We can assume that the statistic is 
Statistical decision  
It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.  
The significance level provided  . The next step would be calculate the p value for this test.
. The next step would be calculate the p value for this test.  
Since is a bilateral test the p value would be:

So the p value obtained was a very high value and using the significance level given  we have
 we have  so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
 so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 5% of significance the true proportion of interest is not different from 3/5
