Test the ability of auto mechanics to identify simple engine problems, an automobile with a single suchproblem was taken to 72 d

jekas [21]

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 $= 42/72=0.5833$

Set up hypotheses as

H0: p =0.75

Ha: p < 0.75

(Left tailed test)

Assuming H0 to be true, std error of proportion = $\sqrt{\frac{0.75*0.25}{72} } \\=0.0668$

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
