Answer:
The proportion is less than 0.75 only
Step-by-step explanation:
given that the ability of auto mechanics to identify simple engine problems, an automobile with a single suchproblem was taken to 72 different car repair facilities.
Sample proportion
Set up hypotheses as
H0: p =0.75
Ha: p < 0.75
(Left tailed test)
Assuming H0 to be true, std error of proportion =
p difference = -0.1667
Test statistic Z = p diff/std error = -2.50
p value = 0.0062
since p is less than0.05 at 5% significance level we reject null hypothesis
The proportion is less than 0.75 only
<h3>Answer:</h3>
Graph (0, 25) and (50, 0)
<h3>Step-by-step explanation:</h3>Intercept form of an equation for a line is ...
- x/(x-intercept) + y/(y-intercept) = 1
Dividing each equation by the constant on the right can put it into this form.
<em>First equation</em>:
- t/42 + f/42 = 1
<em>Second equation</em>:
- t/50 + f/25 = 1
This tells you the second equation can be graphed using the points ...
... (50, 0) and (0, 25) . . . . . matches the second selection
