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

The wall would be 216.72 feet for Joanna’s wall.
Answer:
$525
Step-by-step explanation:
First you calculate 4.5% of $10000
=$10000÷100x4.5
=$450
Then you calculate the 7.5% of the reminder (which is $1000)
=$1000÷100x7.5
=$75
Now you add the two answers
$450+$75
=$525
Answer:
slope intercept form- y=mx+b
m=slope
b=y-intercept
how to find slope= rise/run
how to fine y-intercept= go straight down the y axis (up and down in the center of the graph) until you come across a point
slope=3
y-intercept=-1
answer= 3x-1
