An assembly line will be shut down for maintenance if the defect rate exceeds 1.5%. Suppose you adopt a 2.5% significance level and take a random sample of 300 items from the assembly line and compute the proportion of defective items. For what values of the sample proportion will the assembly line be shut down?
