3. A milling machining operation puts out a finished subassembly whose length has a mean:u = 2.52 ft, and standard deviation o = 0.8 ft. Assume that the process mean, and variance are known.(Use the Constants: Control Chart Constant DM-4 & Constant #1 in our class portala) compute the 3-sigma control limits and the central line for the x-bar and S charts based on asubgroup size of 25.b) what is the probability of not detecting a shift in o to 0.88 ft on the x-bar chart on the first subgroupsampled after the shift (assume the mean stays the same)?c) what is the average number of samples (i.e., the expected number) required to detect the shift in b)above? Give your answers to the nearest whole number.

Approximately 38 percent of people living in Region W have the blood type O positive. A random sample of 100 people from Region X revealed that 35 people in the sample had the blood type O positive. Consider a hypothesis test to investigate whether the percent of people in Region X with O positive blood is less from that of in Region W. Which of the following is the appropriate alternative hypothesis for the investigation? Ha: proportion 0.38 Ha: proportion >0.38 Ha: proportion =0.38 O Ha: proportion <0.38

Control charts for X-bar and s are to be established on the Brinell hardness of hardened tool steel in kilograms per square millimeter. Data for subgroup sizes of 8 are shown below. Determine the trial central line and control limits for the X-bar and s charts. Assume that the out-of-control points have assignable causes. Calculate the revised limits and central line.
A manufacturer of “Keep it Warm” bags is interested in comparing the heat retention of bagswhen used at five different temperatures (100 oF, 125 oF, 150 oF, 175 oF, and 200 oF). Thirty bagsare selected randomly from last week’s production and randomly assigned, six each, to fivedifferent groups. Items from group 1 at beginning temperature 100 oF were kept in bags for anhour, and the temperatures of those items were recorded after an hour. Similarly, groups 2 to 5were assigned items at 125 oF, 150 oF, 175 oF, and 200 oF, respectively.a. Identify the type of study used here.b. What type of inference is possible from this study?
