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:
1) 40
Step-by-step explanation:
The rise between the given points is 120-80 = 40.
The corresponding run is 3 -2 = 1.
Then the rise/run is ...
40/1 = 40 . . . . matches option 1
Answer:
x = 30.63
Step-by-step explanation:
<span>Given the table representing a function.
x 1 2 3 4 5
y 1 16 64 256 1,024
As can be seen from the table, from the value of x = 2, the value of y is given by
i.e.
This represents an exponential function.
Therefore, the </span><span>statement
that would best describe the graph of the function is "The graph starts flat but curves steeply upward."</span>
