A chemical company produces a substance composed of 98% cracked corn particles and 2% zinc phospide for use in controlling rat populations in sugarcane fields. Production must be carefully controlled to maintian the 2% zinc phosphide because too much zinc phosphide will cause damage to the sugarcane and too little will be ineffective in controlling the rat population. Records from past production indicate that the distribution of the actual percentage of zinc phosphide present in the substance is approximately mound shaped with a mean of 2.0% and a standard deviation of 0.08%. If he production line is operation correctly, approximately what proportion of batches from a day's production will contain less than 1.84% of zinc phospide? please guide through answer.
