Juan San America (JSA) is in the business of producing and selling bags containing 40 lbs. of a concrete mix and other ingredients to hardware stores for home improvement projects. Since its inception, the company has used a simple process to produce the mixture. However, in the last year hardware stores have complaints that several of their clients are claiming"...that the average amount of mixture in each bag is less than that stipulated". To learn about the legitimacy of this concern, JSA decided to conduct an experiment taking several random samples (10 bags), hourly, on three consecutive days Based on 3 sigma?, explain if the hardware stores claims have any merit.
