Answer:
1) 
2) 
3) 
Step-by-step explanation:
So we have the two functions:

And we want to find (f+g)(x), (f-g)(x), and (f*g)(x).
1)
(f+g)(x) is the same to f(x)+g(x). Substitute:

Combine like terms:

Add:

So:

2)
(f-g)(x) is the same to f(x)-g(x). So:

Distribute:

Combine like terms:

Simplify:

So:

3)
(f*g)(x) is the same to f(x)*g(x). Thus:

Distribute:

Distribute:

Combine like terms:

Simplify:

So:

Using the z-distribution, it is found that the 95% confidence interval for the true proportion of adults who said that they will travel more this year is (0.347, 0.433).
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 z-score that has a p-value of
.
195 out of 500 people said they would take more vacations this year than last year, hence:

95% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval for the true proportion of adults who said that they will travel more this year is (0.347, 0.433).
