Answer: 86.64%
Step-by-step explanation:
Let x be a random variable that represents the diameter of metal samples.
Given : Population mean :
Standard deviation:
Specified tolerance on the diameter is 0.75 mm.
i.e. range of diameter = 10-0.75< x <10+0.75 = 9.25< x< 10.75
Formula to find the z-score corresponds to x:
At x= 0.75,
Using standard normal table for z-value,
P-value :
∴ Percentage of samples manufactured using this process satisfy the tolerance specification = 86.64%
The correct answer is is D) If the group sells 15 prints they will loose $85.
To figure out which statement is true, we have to evaluate the function ,
for all the values given in options (A)-(D). A negative output represents a loss and a positive output will represent a profit.
In A so
. In this case we gather that if they sell 12 prints, they will make a loss of $136. This tells us that option A is wrong.
In B, so
. In this case we gather that if they sell 28 prints, they make a profit of $136. This tells us that option B is wrong.
In C, so
. In this case we gather that if they sell 35 prints, they make a profit of $225. This tells us that option C is wrong.
Lastly, so
. In this case we gather that if they sell 28 prints, they make a loss of 85 dollars. From this we gather that D is the correct option.
