Answer:
The correct option is (B) 250.
Step-by-step explanation:
A plant can manufacture 100 golf clubs per day for a total daily cost of $7,800.
And 120 golf clubs per day for a total daily cost of $8,400.
Let <em>X</em> = number of golf clubs manufactured per day.
Let <em>Y</em> = total cost of manufacturing golf clubs per day
It is provided that:
(<em>x</em>₁, <em>y</em>₁) = (100, 7800)
(<em>x</em>₂, <em>y</em>₂) = (120, 8400)
Form the least square regression line using two-point form as follows:
The least square regression line to estimate the total daily cost of <em>x</em> golf clubs manufactured daily is:
<em>y</em> = 30 <em>x</em> + 4800
Compute the number of golf clubs manufactured if the total daily cost is $12,300 as follows:
Thus, the correct option is (B).
