Answer:
A
    The  correct option is B
 B 
    
C
  
D
 The  correct option is  D
Step-by-step explanation:
From the question we are told that 
     The  sample size is  
     The  number that developed  nausea  is X =  50 
     The population proportion is  p  =  0.20  
   
The  null hypothesis is   
The  alternative hypothesis is  
Generally the sample proportion is mathematically represented as 
      
      
Generally the test statistics is mathematically represented as 
  =>           
=>           
=>        
 The  p-value obtained from the z-table is 
        
   Given that the   then we fail to reject the null hypothesis
  then we fail to reject the null hypothesis
 
 
        
             
        
        
        
Answer:
3, - 2, - 7, - 12, - 17, - 22
Step-by-step explanation:
To find the first 6 terms substitute n = 1, 2, 3, 4, 5 into the formula, that is
t(1 + 1) = t(1) - 5 ⇒ t(2) = 3 - 5 = - 2
t(2 + 1) = t(2) - 5 ⇒ t(3) = - 2 - 5 = - 7
t(3 + 1) = t(3) - 5 ⇒ t(4)  = - 7 - 5 = - 12
t(4 + 1) = t(4) - 5 ⇒ t(5) = - 12 - 5 = - 17
t(5 + 1) = t(5) - 5 ⇒ t(6) = - 17 - 5 = - 22
