Ratling [72]

Answer:

The null hypothesis is given as H_o : p_1-p_2=0 while the alternate hypothesis is H_A: p_1-p_2\neq 0

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

H_o : p_1-p_2=0

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

H_A: p_1-p_2\neq 0
