Calculate UCL and LCL with "C" control limit !A sample consisting of 10 cartons of Arrow water was taken to measure the degree of salts in the water and the results were shown as follows) = 4.1, 3, 7,5.2, 6.2, 6.1, 5.7, 7, 3.4, 6.5 and whether the production is being used. Find the arithmetic mean panels for single measurements, the upper bound and The limit is the one.A random sample of size n = 225 is to be taken from an exponential population with θ = 4. Based on the cen-tral limit theorem, what is the probability that the mean of the sample will exceed 4.5?
- a series of 20 samples of size 4 has been drawn from a project. the measure of interest has an average of 23.7 and the average range within the sample is 3.51 determine the control chart upper limit for x-bara series of 20 samples of size 4 has been drawn from a project. the measure of interest has an average of 21.54 and the average range within the sample is 2.57 determine the control chart upper limit for RA new process to produce synthetic diamonds can be operated at a profitable level only if their average weight is greater than 0.5 carats. To evaluate the profitability of the process, six diamonds are generated with weights of 0.46, 0.61, 0.52, 0.48, 0.57 and 0.54 carats. Do these six measurements present enough evidence to indicate that the average weight of the diamonds produced by the process is more than 0.5 carats? Calculate the lower limit for µ of 95% using a lower confidence limit.
- Some of the 100 batteries of the same type produced in a day at the factory that manufactures various batteries were simply randomly selected to measure their lifetimes. The data obtained are given in the table below. a. Estimate the average life of the batteries in question. Calculate the estimation error limit.b. Estimate the total life of the batteries. Calculate the estimation error limit.c. Estimate the proportion of batteries that can be used for more than 1000 hours. Calculate the estimation error limit.d. In a similar future study, using the values you obtained in (c) as preliminary information, how many batteries should be chosen to estimate the proportion of batteries that can be used for more than 1000 hours with an error of 0.2 units?e. Compare and interpret what you get in (c) and (d).A random sample of 70 printers discovered that 25 of them were being used in small businesses .
