Using the z-distribution, as we are working with a proportion, it is found that there is enough evidence to conclude that the proportion is different of 50%.
<h3>What are the hypothesis tested?</h3>At the null hypothesis, it is tested if the proportion is of 0.5, that is:
At the alternative hypothesis, it is tested if the proportion is different of 0.5, that is:
.
The test statistic is given by:
In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
- n is the sample size.
In this problem, the parameters are:
Then, the value of the test statistic is as follows:
Considering a <em>two-tailed test</em>, as we are testing if the proportion is different of a value, with a <em>significance level of 0.05</em>, the critical value is of .
Since the absolute value of the test statistic is greater than the critical value for the two-tailed test, it is found that there is enough evidence to conclude that the proportion of participants that had improved androstenone-detection accuracy is different of 50%.

The appropriate choice is
A. 5 and 6
The equation can be rewritten as
6x -16u = -66
or
3x -8u = -33
___
The graph shows where the various answer options lie in relation to the line described by the equation. Only (5, 6) lies on the line, so that is the only appropriate set of values for (x, u).
