Question
Records from an electronics company show that the average number of circuit boards rejected per batch5.2has a variance of1.4. Due to a change in the molding process, you have been hired by the factory management to perform a hypothesis test to verify if the varianceo²,It has increased. To do this, test a random sample ofelebatches produced with the new process; the number of circuit boards rejected per lot has a sample variance of2.4. Under the assumption that the number of circuit boards rejected per lot using the new process follows a normal distribution, perform a chi-square test. Findx², ,the value of the test statistic for the chi-square test. Round your answer to three or more decimal places. 2 2 x² = 0 S
