Answer:
The null hypothesis is given as 
while the alternate hypothesis is 
Step-by-step explanation:
As per the the given data
p1=Proportion of Homeowners who would buy the security system
p2=Proportion of Renters who would buy the security system
As the null hypothesis states that there is no difference in the test thus it is given as
This states that there is no difference between the probabilities of the homeowners buying the security system and the renters buying the security system.
The Alternative hypothesis is the other possibility of the null hypothesis. i.e It negates the null Hypothesis and is given as

Answer: $7.70
Step-by-step explanation:
Given : A box contains eighteen $1 bills, ten $5 bills, eight $10 bills, three $20 bills, and one $100 bill.
Total bills = 
We know that probability of any event =
i.e. the probability of getting $1 bills =
Probability of getting $10 bills =
Probability of getting $5 bills =
Probability of getting $20 bills =
Probability of getting $100 bills =
Hence, the expected value of your draw= $7.70
90 + 8 ? What are you asking? :)
