(a)

Summary Introduction

To determine: The upper and lower control limits that include roughly 97% of the sample means when an automatic machine filled a one-liter bottle of cola with a mean of 1 liter, a standard deviation of 0.1 liters, and samples of 25 observations are used to monitor the output.

Introduction: To monitor the process dispersion, range control charts are used and the mean control limit charts are based on a normal distribution.

(b)

Summary Introduction

To determine: Whether the process is in control at the sample means: 1.005, 1.001, .998, 1.002, .995, .999 when an automatic machine filled a one-liter bottle of cola with a mean of 1 liter, a standard deviation of 0.1 liters and samples of 25 observations are used to monitor the output.

Introduction: To monitor the process dispersion, range control charts are used and the mean control limit charts are based on a normal distribution.

(c)

Summary Introduction

To determine: Whether the process is in control at sample means of 1.003, .999, .997, 1.002, .998, and 1.004. when an automatic machine filled a one-liter bottle of cola with a mean of 1 liter, a standard deviation of 0.1 liters and samples of 25 observations are used to monitor the output.

The Carbondale Hospital is considering the purchase of a new ambulance. The decision will rest partly on the anticipated mileage to be driven next year. The miles driven during the past 5 years are as follows: Year Mileage 1 3,000 2 3 4 4,000 3,450 3,850 5 3,800 a) Using a 2-year moving average, the forecast for year 6 = miles (round your response to the nearest whole number). b) If a 2-year moving average is used to make the forecast, the MAD based on this = miles (round your response to one decimal place). (Hint: You will have only 3 years of matched data.) c) The forecast for year 6 using a weighted 2-year moving average with weights of 0.40 and 0.60 (the weight of 0.60 is for the most recent period) = ☐ miles (round your response to the nearest whole number). miles (round your response to one decimal place). (Hint: You will have only 3 years of The MAD for the forecast developed using a weighted 2-year moving average with weights of 0.40 and 0.60 = matched data.) d) Using…

Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Activity Time (weeks) Immediate Predecessor(s) Activity Time (weeks) Immediate Predecessor(s) A 6 E 3 B B 8 F 6 B C 3 A G 11 C, E D 1 A H 7 D, F Dave's earliest start (ES) and earliest finish (EF) are: Activity ES .EF A 0 6 B 0 8 C 3 9 D 6 E F 8 G 22 H 21 Dave's latest start (LS) and latest finish (LF) are: Activity LS LF H 15 G 11 F 9
