Answer:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
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:

99% 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 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
Answer:
44 units² or 44 units squared
There really isn't a preference of units, like inches or meters, so you can add that in.
Step-by-step explanation:
Haha, this is what we're doing in class!
Okay, so the formula for a trapezoid is A= ½ (b1+b2) h
14= b1
8= b2
Add them... You get 22. Multiply that by the height, which is 4. You should get 88. Then divide by 2. You should get 44.

If this is a true or false question, the answer is false. Capacity is space, or how much space there is.
To answer this we need to divide 12,000 by 10 and our answer will be the tenth of 12,000. Then we will check our work. Lets do it:-
12,000 ÷ 10 = 1,200
1,200 is the tenth of 12,000.
CHECK OUR WORK:-
1,200 × 10 = 12,000
We were RIGHT!!
So, 1,200 is the tenth of 12,000.
Hope I helped ya!!
