Answer:
For the first question the sample size is n= 3850
And replacing we got:
We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.
Step-by-step explanation:
We have the following info given:
represent the estimated proportion of all people who like the movie
represent the sample size selected
For the first question the sample size is n= 3850
For the second part they gives to us the margin of error:
We know that the confidence interval for a population proportion 
of interest is given by:
And the margin of error is given by:
So then the confidence interval can be found with this formula:
And replacing we got:
We are confident at 95% that the true proportion of all people who like the movie is between 0.484 and 0.516.

Answer:
2. x ≈ 17.74
3. x ≈ 16.64
Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan
__
2. x = 32×tan(29°) ≈ 17.74
3. x = 13×tan(52°) ≈ 16.64
_____
Hopefully, we've given enough decimal places so that you can round to the precision you need.
