Answer:
<em>Question 1) </em>
The graph of 
is attached to the answer.
The graph of such a functio lies in first and third quandrant such that the graph tends to 0 when x→∞ or when x→-∞ and graph tends to ∞ when x→0.
We can also show the values of this equation on a table:
<u> x-values</u> <u> y-values</u>
1/2 4
1 2
2 1
3 2/3
<em>Question 2)</em>
The graph of the equation 
is attached to the answer.
we will get a upward parabola with this equation whose vetex is: (-1,-4).
The ordered pair on the graph could be shown with the help of a table:
<u>x-values</u> <u> y-values</u>
-1 -4
0 -3
-3 0
1 0
Answer:
Step-by-step explanation:
The question is incomplete. The complete question is:
An insurance company reported that, on average claims for a certain medical procedure are $942. an independent organization constructed a 95% confidence interval of ($930, $950) for the average amount claimed for the particular medical procedure. what conclusion best evaluates the truthfulness of the number reported by the insurance company?
a) with 95% certainty, the average claim for this medical procedure is $942.
b) with 95% certainty, the average claim for this medical procedure is not $942.
c) the confidence interval is consistent with an average claim of $942 for this medical procedure
Solution:
Confidence interval is used to express how confident we are that the population parameter that we are looking for is contained in a range of given values. Looking at the given confident interval, the lower limit is $930 and the upper limit is $950. We can see that the population mean, $942 lies within these values. The correct option would be
c) the confidence interval is consistent with an average claim of $942 for this medical procedure
