Answer:
The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
90% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the population proportion who knew about the incentives is (0.28, 0.44).
Answer:
y=-x+2
Step-by-step explanation:
Take two points and solve for the slope using: (y2-y1)/(x2-x1)=m
Then take the slope and plug it into the slope-intercept equation, y=mx+b.
Finally, take a xy pair and plug it into your equation to solve for b.
If a person bought 8 items and each item was priced at $4, that means the total amount spent was $32.
The person received 8 dollars in change. This means that the person payed 8 dollars more than what they spent. Well, we just found out how much they spent, so we can find out how much money the person gave the vendor.
Let p = amount of money paid by the person.
The person gave the vendor $40.
