7. We would like to modify the quality control test described in question 6 above in the following way. We want to pass the shipment if X w where w is a number to be determined. Determine the smallest possible value for w such that the probability of rejecting the shipment when p = .05 is no more than .01, i.e., 1%.6. You are considering a quality inspection scheme to use on the spark plugs which are sent from your supplier. These spark plugs come in a shipments of 50,000. Denote the unknown proportion of defective spark plugs in the shipment by p. Ideally you would like to reject the shipment if p > .05 and accept it if p g .05. In practice you can't follow this plan since you don't know 39. Instead you decide to apply a scheme that consists of the following steps: A random sample of 20 of the Spark plugs will be selected from each shipment (assume that the sample is selected with replacement). Each of the selected plugs will be tested to see whether it is defective or not. (The test involves measuring the plug gap and determining the electrical resistance.) You will note as X the (random) number of defective plugs in the sample. If X
