Answer:

the total surface area is 40 + 12 + 15 = 67 square units

Step-by-step explanation:

Refer to the diagram:  

the combined area of the top and bottom is 2(5·4) = 40:

the combined area of the ends is 2(1.5·4) = 12; and

the combined area of the front and back is 2( 5 · 1.5) = 15

and so the total surface area is 40 + 12 + 15 = 67 square units

Because of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manuf
7nadin3 [17]

Answer:

See explanation below

Step-by-step explanation:

Here, a director of manufacturing must convince management that a proposed manufacturing method reduces costs before the new method can be implemented. The current production method operates with a mean cost of $220 per hour.

a) The alternative and null hypotheses would be:

H0: μ ≥ 220

Ha: μ < 220

b) Comment on the conclusion when H0 cannot be rejected:

When we fail to reject the null hypothesis H0, there is not enough evidence to conclude that the mean cost can be reduced from $220. Therefore the manager's proposed method cannot be implemented.

c) Comment on the conclusion when H0 can be rejected:

When the null hypothesis, H0 is rejected, there is enough evidence to conclude that the mean cost can be reduced from from $220. Therefore the manager's proposed method can be implemented.
