Answer:

a. We get 56 heads out of 100 tosses. 
We will use one sample proportion test  
x = 56
 n = 100 



Formula of test statistic =
                                        =
                                        =
refer the z table for p value 
p value = 0.8849
a.  We get 560 heads out of 1000 tosses.

                                        =
refer the z table for p value 
p value = .000148
p value of part B is less than Part A because part B have 10 times the number the tosses.
 
        
             
        
        
        
Answer:
3/5
Step-by-step explanation:
We want to find 3/4 of 4/5. 
The keyword <em>of</em> tells us that we need to multiply. Therefore: 

Multiply: 

So, 3/4 of 4/5 is 3/5. 
We can confirm this by converting them to decimals. 
4/5 is 0.8. 
3/4 is 0.75. 
0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
