Answer:
The graph of the function is attached below.
Step-by-step explanation:
Considering the function
<u><em>Determining x-intercept:</em></u>
Using the logarithmic definition
so the x-intercept = (1000, 0)
<u><em /></u>
<u><em>Determining y-intercept:</em></u>
Therefore, the graph of the function is attached below.
The confidence interval is
.
This means that if we take repeated samples, 99% of the intervals would contain the population proportion.
To construct this interval, we use
,
where
Since 590/1016 said they had a cat and a dog, p=0.581 and N=1016:
We need the z-score associated with this confidence level:
Convert 99% to a decimal: 99/100 = 0.99
Subtract from 1: 1-0.95 = 0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table, we see that this value is equally distant from z=2.57 and z=2.58, so we will use z=2.575:
