Many properties of the fabric used in different textiles, such as sheets and clothing, are influenced by whether the diameter of yarn used in the creation of the textiles consistent. Therefore, various methods can be used to measure the diameter of yam at specified intervals, such as every 2 mm, to determine the consistency of the diameter. These measurements are normally distributed. Suppose that one textile manufacturer will not use any yarn in which the variance of the diameters is greater than 0.0025 mm. In order to ensure that the yarn is usable, the diameter of a length of yarn is measured at 300 random intervals. The variance of those menurements is found to be 0.003015 rum Does this evidence provide support that the batch of yarn i unutable by the manufacturer? Use a 0.10 level of significance Step 2 of 3: Compute the value of the test statistic Round your answer to three decimal places
