The control chart is given above. Hence option (c) is correct.
All the points are between the control limits, so the process appears to be in control.

can u clearly show me how to find a sample size (N) , A2, and
can you also tell me why we are using an X Chart?
Problem 1 A restaurant wants to control kitchen preparation time of dinner meals using an X chart. The process standard deviation is unknown. Each evening a manager takes a random sample of 14 dinner orders and measures and records their kitchen preparation time. Create an X Chart using data in the table below...
a) What is null hypothesis in terms of voltage readings?

1. A production process is designed to fill boxes with an average of 14 ounces of cereal. The population of filling weights is normally distributed with a standard deviation of 3 ounces. a. Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the x¯x¯ chart if samples of 12 boxes are taken. (Round the value for the centerline to the nearest whole number and the values for the UCL and LCL to 3 decimal...
Suppose samples of six different brands of diet or imitation margarine were analyzed to determine the level of physiologically active polyunsaturated fatty acids (PAPUFA, in percent), resulting in the data shown in the accompanying table.

7.Physical Characteristics of sharks are of interest to surfers and scuba divers as well as to marine researchers. Because it is difficult to measure jaw width in living sharks, researchers would like to determine whether it is possible to estimate jaw width from body length, which is more easily measured. The following data on x = length (in feet) and y = jaw width (in inches) for 44 sharks was found in various articles appearing in the magazines Skin Diver...
10) A battery manufacturer is developing a new battery to be used for the iPhone 10. Before they will switch to the new design, they need to verify that the new battery will outperform (measured as hours of continuous music play) the current battery. a) State the Hypothesis to show the new battery design has longer playing time than the current battery design. b) Choose a level of a. Use a = 0.05 for this problem. c) To test the...
