Answer:
Sample number 3
Step-by-step explanation:
From the given information:
Sample Service life(hours) Total Mean(X)
1 2 3 4
1 495 500 505 500 2000 500
2 525 515 505 515 2060 515
3 470 480 460 470 1880 470
Total =
Mean =
Thus;
To plot on an X_Bar chart, we have:
Sample Mean (X) UCL LCL
1 500 520 480
5 515 520 480
6 470 520 480
The x-Bar chart is shown in the image attached below. From the image, we realize that the average service life for sample number 3 occurs to be out of the statistical control.
Very interesting wording but from what I gathered, scaling down by a factor of 1/10 would be 64- 6.4(1/10 of 64) so your final answer would be 57.6
Hope this explanation helps ;)
Answer:
27 purple marbles are there
Step-by-step explanation:
P = 2B + 5
P + B = 38
P = 2 x (38 - P) + 5
= 76 - 2P + 5
= 81 - 2P
3P = 81
P = 27
