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
Answer: there’s no one question though
Step-by-step explanation:
Answer:
Bases change red litmus into blue and bases have a slippery and soapy texture. Therefore, we can conclude that out of the given options, one way to test whether an unknown solution is acidic or basic is to check whether the solution has a slippery feel
Step-by-step explanation:
To solve this, you plug in the points into each eaquation and solve. If the equation is true, the point is on the line.
D is the answer
