Mr. Mastrogiacomo is testing the hypothesis that the proportion of households in a large town that have high-speed internet service is equal to 0.7 against the alternative that the proportion is different from 0.7. What is the chief advantage of using a confidence interval to test this hypothesis rather than a significance test
Step-by-step explanation:
You can use a confidence interval (CI) for hypothesis testing. In the typical case, if the CI for an effect does not span 0 then you can reject the null hypothesis. But a CI can be used for more, whereas reporting whether it has been passed is the limit of the usefulness of a test.

You put $900 into an account earning 2% interest compounded continuously. Find the amount in the account at the end of 12 years.
Given:
Principal value = $900
Rate of interest = 2% compounded continuously.
Time = 12 years.
To find:
The amount in the account at the end of 12 years.
Solution:
If the interest compounded continuously, then the formula for amount :
[tex]A=Pe^{rt}[/tex]
Where, P is principal, r is rate of interest, t is numbers of years.
Putting P=900, r=0.02 and t=12, we get
[tex]A=900e^{0.02(12)}[/tex]
[tex]A=900e^{0.24}[/tex]
[tex]A=1144.12423529[/tex]
[tex]A\approx 1144.12[/tex]
Therefore, the amount in the account at the end of 12 years is about $1144.12.

Multiply, add the products, round UP and multiply times 6.
NOTE: Why round up? because if you need, for example, 1.22 gallons, you have to get 2 gallons. If you buy just 1 you'll be short, and you can't buy 0.22 of a gallon.

7 freinds to a party if each freind will get 5 cookies and each box has 12 cookies how many boxes does shenika need to get
Answer:
3 boxes
Step-by-step explanation:
To find the answer for the problem consider the amount of friends and how many cookies they will receive
First multiply 5 and 7 to find the amount of cookies she needs
5 x 7 = 35
She needs 35 cookies but there are 12 cookies per box
36 / 12 is 3
We are using 36 because it is the closest number to 35 that 12 can go into
She needs to get 3 boxes in order for each friend to get 5 cookies
Hope I helped :]
Answer:
Shenika needs to get 3 boxes.
Step-by-step explanation:
7 friends x 5 cookies each = 35 cookies needed.
12 cookies in each box.
12 x 3 = 36 cookies.

To celebrate getting a new job, Marco went out for a dinner that cost $100. If the localsales tax is 6% and Marco left a 15% tip on $100, what was the total cost of his meal?
Answer:
$121
Step-by-step explanation:
So if the meal cost $100, finding out the percentages is pretty easy.
The sales tax is 6%, and 6% of 100 is simply 6.
15% of 100 is simply 15.
So, adding the total cost of the meal plus the sales tax plus the tip is simply $121.

You had $22 to on four raffle tickets . After buying them you had $6. How much did each raffle ticket cost?
Answer:
X=4
Each raffle ticket cost 4 dollars
Step-by-step explanation:
22-4x=6
solve
-4x=-16
Divide
x=4
Answer: 4 bucks
Step-by-step explanation: 22 bucks at first
You buy four tickets, then you have 6 bucks
If the amount spent is x, then 22 - 4x = 6, so -4x + 22 =6
22 minus 22 is 0, cancel it out — 6 minus 22 is -16
-4 divided by -4 is 0, now you only have x. -16/-4 = 4
X = 4, 4 bucks per raffle ticket
