---**COMPUTATIONAL PROBLEM (Values for a Control Chart)**A company that makes balloons controls its production process by periodically taking a sample of 100 balloons from the production line. Each balloon is inspected for defective features. During the last 6 samples taken, the proportion of defective items per sample was recorded, as shown in the image below. Which answer below is correct for the center line, the upper control limit, and the lower control limit, respectively (meaning, in that order)? You will need to carry 4 decimal places in your computations.| Sample # | Percent Defective ||----------|-------------------|| 1 | .02 || 2 | .01 || 3 | .04 || 4 | .03 || 5 | .01 || 6 | .02 |---In this problem, a table is provided that lists six samples along with the corresponding percentage of defective balloons for each sample. To solve this problem:1. **Center Line Calculation**: - Calculate the average proportion of defective items for all the samples.2. **Control Limit Calculations**: - Use the average proportion defective, standard deviation, and appropriate control chart factors to determine the upper control limit (UCL) and lower control limit (LCL).This material is designed to help students learn how to compute control limits for quality control charts in a manufacturing setting.

7. The school board is trying to evaluate a new math program introduced to second-graders in five elementary schools across the county this year. A sample of the student scores on standardized math tests in each elementary school yielded the following data: School No. of Test Errors A 48 B 21 C 32 D 40 E 52 For the test errors, the c-chart with control limits that contain 99.73% of the random variation in test scores is: _____ Part 2 UCLc= _______ (round your response to two decimal places). LCLc= _______ (round your response to two decimal places). What does the chart tell you? Has the new math program been effective?

The output of a certain integrated-circuit productionline is checked daily by inspecting a sample of 100 units.Over a long period of time, the process has maintaineda yield of 80 percent, that is, a proportion defective of 20 percent, and the variation of the proportion defec-tive from day to day is measured by a standard devi-ation of 0.04. If on a certain day the sample contains 38 defectives, find the mean of the posterior distribu-tion of as an estimate of that day’s proportion defec-tive. Assume that the prior distribution of Θ is a beta distribution.
The purpose of control charts for variables is to ensure that process variation is random and meets standards Select one: O a. TRUE Ob. FALSE
