Expert Solution & Answer
To determine
To define the range names for each of these samples and then use the range names in formulas to find the average values of each samples.
Explanation of Solution
Given:
The Syringe samples data for the fifteen samples in the excel file is as follows:
| Sample | Sample Observations | ||||
| S1 | 4.9600 | 4.9460 | 4.9500 | 4.9560 | 4.9580 |
| S2 | 4.9580 | 4.9270 | 4.9350 | 4.9400 | 4.9500 |
| S3 | 4.9710 | 4.9290 | 4.9650 | 4.9520 | 4.9380 |
| S4 | 4.9400 | 4.9820 | 4.9700 | 4.9530 | 4.9600 |
| S5 | 4.9640 | 4.9500 | 4.9530 | 4.9620 | 4.9560 |
| S6 | 4.9690 | 4.9510 | 4.9550 | 4.9660 | 4.9540 |
| S7 | 4.9600 | 4.9440 | 4.9570 | 4.9480 | 4.9510 |
| S8 | 4.9690 | 4.9490 | 4.9630 | 4.9520 | 4.9620 |
| S9 | 4.9840 | 4.9280 | 4.9600 | 4.9430 | 4.9550 |
| S10 | 4.9700 | 4.9340 | 4.9610 | 4.9400 | 4.9650 |
| S11 | 4.9750 | 4.9590 | 4.9620 | 4.9710 | 4.9680 |
| S12 | 4.9450 | 4.9770 | 4.9500 | 4.9690 | 4.9540 |
| S13 | 4.9760 | 4.9640 | 4.9700 | 4.9680 | 4.9720 |
| S14 | 4.9700 | 4.9540 | 4.9640 | 4.9590 | 4.9680 |
| S15 | 4.9820 | 4.9620 | 4.9680 | 4.9750 | 4.9630 |
Formulas used:
Let the range names be
| S1 | S2 | S3 | S4 | S5 | S6 | S7 | S8 | S9 | S10 | S11 | S12 | S13 | S14 | S15 |
And the formulas used for the average is:
=AVERAGE(S1), =AVERAGE(S2), and so on for fifteen samples.
Calculation:
We will apply the formula of the average in each of the samples to find out the result.
Thus, the outcome of the result is as follows:
| Sample | Sample Observations | Average | ||||
| 1 | 4.9600 | 4.9460 | 4.9500 | 4.9560 | 4.9580 | 4.9540 |

A quality characteristic of a product is normally distributed with mean μ and standard deviation σ = 1. Speci-
fications on the characteristic are 6≤x≤8. A unit that falls within specifications on this quality characteristic
results in a profit of Co. However, if x 8, the profit is -C2. Find the value
ofμ that maximizes the expected profit.
A) The output voltage of a power supply is normally distributed with mean 5 V and standard deviation 0.02 V. If
the lower and upper specifications for voltage are 4.95 V and 5.05 V, respectively, what is the probability that a
power supply selected at random conform to the specifications on voltage?
B)
Continuation of A. Reconsider the power supply manufacturing process in A. Suppose
We wanted to improve the process. Can shifting the mean reduce the number of nonconforming units produced?
How much would the process variability need to be reduced in order to have all but one out of 1000 units conform
to the specifications?
