Managers at an automobile manufacturing plant would like to estimate the mean completion time of an assembly line operation, . T
Vinil7 [7]

Answer:

The appropriate answer is "144".

Step-by-step explanation:

Given:

Population standard deviation,

\sigma=10.4

Margin of error,

E=1.7

CL=95 %

CL=1-\alpha

Or,

\alpha=1-CL

  =1-0.95

  =0.05  

Now,

Critical value,

= Z_{\frac{\alpha}{2} }

= Z_{\frac{0.05}{2} }

= 1.96

The minimum sample size will be:

⇒ n=\frac{Z^2_{\frac{\alpha}{2} }(\sigma)^2}{E^2}

By putting the values, we get

       =\frac{(1.96)^2(10.4)^2}{(1.7)^2}

       =\frac{415.5074}{2.89}

       =143.774

or,

       =144
