A sample of silty clay was found by immersion in mercury to have a volume of 17.87 mm, while its mass at natural moisture content was 30 g and the particle specific gravity was 2.7. Calculate the void ratio, e, and degree of saturation, S, if, after oven-drying, the sample had a mass of 25.9 g.

The manufacturer bakery had provided us with their specification limit, which was 145 g -155 g. Out of the 50 biscuit packets, it was observed that 5% weighed between 145.5 g and 146 g while 2% of the packets weighed between 153.95 g and 154.5 g. Which of the following groups can be categorised as bad quality? The 5% of the sample that weighed between 145.5 g and 146 g.  The 2% of the sample that weighed between 153.95g and 154.5g.  Both of the groups. None of the above.

Question 2: The account receivable department of R&W Company has received complaints from manycustomers about incorrect billing, i.e., the bills do not reflect the materials that arrived at their receivingdocks. The department has decided to implement statistical process control in its billing process. Randomsamples of 60 bills each were taken over 8 days and the items on the bills checked against the bill of ladingsent by the company’s shipping department to determine the number of incorrect bills. The observationis given below: Day 1 2 3 4 5 6 7 8 No. of Incorrect Bills 3 13 5 12 9 1 3 2                   a. You want to develop appropriate control chart(s) to check whether the process is in control.i. Find the control limitsii. Plot the control chart(s) in excel.b. Is the process in control? Give reason for your answer.
