Answer:
x = 4/5
Step-by-step explanation:
The x-intercept looks like (x, 0); the coordinate 0 indicates that the point lies on the x-axis. If we start with 4/5x + 1/3 y= 1 and let y = 0, we will get an equation for the x-intercept:
(4/5)x + (1/3)(0) =1
Then 4/5x = 1, and (5/4)(4/5)x = (1)(4/5).
Thus, x = 4/5, and the x-intercept is (4/5, 0).
Considering the situation described, the appropriate null hypothesis is given by:
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if the proportion is the expected one, that is, of 9%, hence:
At the alternative hypothesis, it is tested if there is enough evidence to conclude that the proportion is above 9%, hence:
.
