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

How do I solve this problem? This is Linear funct
grandymaker [24]
I would use a proportion for the Fred's Fouls part. Use the closest point to 12 possible, which is (15, 69.5).
Set up the proportion like so:
15/69.5 = 12/x
Now cross multiply.
15x = 834
Now divide both sides by 15 to get x by itself.
x = 55.6
Fred's Fouls will charge $55.60 for 12 wings.
Now plug in 12 as x for the Carlie's Chicken part and solve for f(12).
f(12) = 3.75(12) +10
f(12) = 45 +10
f(12) = 55
Carlie's Chicken will charge $55 for 12 wings.

Answer:

B

Step-by-step explanation:

Multiplying something by 10^-1 is just dividing it by 10.

So 3.02 / 10 = 0.302 since the decimal point moves one to the left.

Answer:

We use both median and mean to give us a sense of what the 'average' or middle of a group looks like. It may be the case that the median and mean of a given set of data are very similar. Take the data set above, for example. ... When values are evenly distributed, the mean will be similar to the median
