Answer:
Can you explain clearer?

First we can change the miles per hours into feet per hour. Every mile is 5280 feet so multiply 58 by 5280. 58*5280=306,240. Now you have 306,240 feet per hour which you then divide by 60 twice to get per second. 306,240/60=5,104ft per minute now divide again to find per second. 5,104/60≈85.1feet per second.
        
                    
             
        
        
        
Answer:
We fail to reject the null hypothesis at 0.05 significance level. We cannot say that less than 12% of trips include a theme park visit.  
Step-by-step explanation:
let p be the proportion of trips included a visit to a theme park.
 : p=0.12
: p=0.12
 : p<0.12
: p<0.12
To test, we need to calculate test statistic of the sample proportion as:
z= where
 where 
- p(s) is the sample proportion of trips included visit to a theme park ( 
- p is the proportion assumed under null hypothesis. (0.12)
- N is the sample size (1565)
Using the numbers, z= 
 
= −0.767 and p(z) is ≈0.222 
Since 0.222 > 0.05 we fail to reject the null hypothesis.
