Answer:
Explanation:
Experiments were performed for 240 people, 60 people test positive.
Step 1: we calculate the sample proportion; p= 60/240= 0.25.
Step 2: calculate the standard error for the sample, which is the square root of sample proportion,p = p(1-p)/n, n=100
0.25(1-0.25)/100
= 0.04.
Step 3: calculate the test statistics; assuming the hypothesis test percentage is 25%
Then, we say 0.25-1=0.75
-0.75/0.04
= -1.875.
In particular, the sample results are -1.875 standard error.
Probability of Z is less than -1.875.
Look up it value in the Z table
I think it “A law of demand”?
Answer:
Chair unit cost: $ 49.72
Total cost for 675 chairs: $ 33,561
Explanation:
Direct Materials: $ 14.00
Direct Labor: 1.9 hours x $16 labor cost: $ 30.40
Overhead:
1.9 labor hours x ($ 1.6 variable rate + $ 1.20 fixed rate) = $<u> 5.32 </u>
Total unit cost: $ 49.72
Cost to produce 675 chairs:
675 charis x $ 49.72 per chair = $ 33,561
Answer:
Here the situation can be termed as the straight re buy.
