Explanation Calculation: The given information is that, in a simple random sample 14 out of 200 electric circuits are defective which are taken from a large shipment. From the information it is observed that number of defective electric circuits and total number of electric circuits are provided for which only proportion is possible to obtain and the confidence interval that is asked to construct is also for the proportion of circuits that are defective. Hence the population parameter is the type of parameter that is to be estimated. The population proportion of the defective electric circuits is calculated below, p = 14 200 = 0.07 . Confidence interval: Software procedure: Step-by-step software procedure to obtain the confidence interval using MINITAB software is as follows, Choose Stat > Basic Statistics > 1-Proportion
