Answer: Null hypothesis: 
Alternative hypothesis: 
Step-by-step explanation:
- A null hypothesis is a type of hypothesis that states that there is no difference between a particular parameter of a population whereas an alternative hypothesis states that there is a difference.
Given: p = Proportion of all marketing researchers who disapprove of the actions taken in the conflict of interest scenario.
n= 200
Sample proportion = 
Claim : p>0.50
Null hypothesis: 
Alternative hypothesis: 
1 3 1
--- * ---- = ------ = 1/24
9 8 3*8
The answer to your question is 136
F=p(1+rt)
6200=5000(1+6r) divided both sides by 5000
1.24=1+6r
1.24-1=6r
6r=0.24
R=0.04*100=4%
X=12/11 for the first one
