To prove your integrity, you weighed 4 chocolate truffles coming out of production in the last five working days. The data is as below (weights are in grams).

Mon Tue Wed Thu Fri

10am 30.50 30.30 30.15 30.60 30.15

11am 29.75 31.00 29.50 32.00 30.25

2pm 29.90 30.20 29.75 31.00 30.50

3pm 30.25 30.50 30.00 30.00 29.70

(Background: The required weight for a truffle is 30.5 gram, but the company allows an average 0.5 gram change in the daily operations.)

Task 1: Draw the x-bar and R charts and determine whether the process is in-control.

Task 2: Assume:

Target value = 30.5

Upper specification limit (USL) = 31

Lower specification limit (LSL) = 30

What is the capability index of the process? samples satisfy the design specification?

studying for finals and just dont understand these questions. sample question for a final thank you for the help
